[Kernel-packages] [Bug 1752772] Re: r8169 ethernet card don't work after returning from suspension

[Kai-Heng Feng]

Can you try latest mainline kernel again? At least the issue is gone for
me with latest mainline kernel.

I'll do a reverse bisect to find the commit that fixes the issue, and
backport the patch to Bionic's kernel.

Title:
  r8169 ethernet card don't work after returning from suspension

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have noticed that the network stopped working on my desktop after
  I've suspended the system and woke it up. On dmesg there are messages
  like:

  [  150.877998] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready
  [  150.944101] do_IRQ: 3.37 No irq handler for vector
  [  150.944105] r8169 :01:00.0 enp1s0: link down
  [  150.944180] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready

  When using Xenial (from a different install), this problem is not
  happening. This is happening on Bionic.

  There are only two ways to restore connectivity: 
  1) Reboot the system;
  2) Remove the r8169 module and reinsert it with modprobe.

  The motherboard is a AsRock H55M-LE and the Ethernet controller is:

  01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

We need to make progress in testing other firmware and guest issues. We
will come back to this later.

Meanwhile, the problem happened again today with the reboot and we tried
to collect the vmcore using 'X', but it did not collect. Indira, pls add
those details.

  Bluetooth doesn't reconnect to my headsetup post resume from sleep

Status in bluez package in Ubuntu:
  New

Bug description:
  Steps to repro:

  * Cold boot the laptop
  * Pair it with bluetooth headset
  * Listen to music
  * Turn off the headset or turn off the bluetooth on the laptop
  * Play music, sound comes out of the laptop speakers
  * Turn on the headset back on or the bluetooth on the laptop
  * Headset reconnects with the laptop and audio plays from the headset

  -- all the above is expected --

  * Suspend the laptop
  * wait a minute or two for the headset to power down
  * Resume the laptop
  * Turn on the bluetooth headeset
  * It doesn't automatically reconnect to the laptop (not expected behaviour)
  * Launch Gnome Settings and select Bluetooth and force the headset to connect
  * It connects for 2 seconds then disconnects (not expected behaviour)

  The only to get the headset to reconnect again is by restarting the
  bluetooth.service using systemctl.

[Kernel-packages] [Bug 1761751] Re: Black screen on 18.04 + AMD RX460

[David Henningsson]

Kernel 4.15rc2+78d9b048446c3c0a83313444fb706f8f3bccdae7: Black screen.

Note: I installed the linux-image-...-generic deb only as the header
ones seemed to require libssl1.1...?

Anyway, I did some research on my own as well.

First, I had a look at the commits between 4.15rc2 and 4.15rc3. The only
one I could see being relevant is this one:

commit a703c55004e1c5076d57e43771b3e7796ea0
Author: Daniel Vetter 
Date:   Mon Dec 4 21:48:18 2017 +0100

drm: safely free connectors from connector_iter

...it seems relevant because the error I get is "Cannot find any crtc or
sizes", and the code emitting this error message (in
drivers/gpu/drm/drm_fb_helper.c) deals with connectors.

This commit is then referenced in other commits later on as being
required to fix, but since 4.16 is "black screen" too those fixes seems
not have helped here.

  Black screen on 18.04 + AMD RX460

Status in linux package in Ubuntu:
  In Progress
Status in linux source package in Bionic:
  In Progress

Bug description:
  I've been running 16.04 + hwe kernel 4.15 for a while now and recently
  I'm now having a black screen instead. I've also tried an 18.04 daily
  live USB stick, which has the same issue.

  It probably started during an upgrade this week or last week. As a
  start I'm blaming the Linux kernel since booting a 4.13 kernel works
  just fine.

  Known faulty kernel versions are:
   * linux-image-4.15.0-041500-generic (mainline kernel),
   * linux-image-4.16.0-041600-generic (mainline kernel),
   * linux-image-4.15.0-13-generic (Ubuntu kernel),
   * whatever comes with 18.04 daily live USB stick as of 20180404.

  Not sure how to best collect logs and system information for you since
  I'm not used to debugging black screens, so I'm just attaching lspci
  as a start.

  EDIT: Workaround found by adding "amdgpu.dc=0" to kernel boot
  parameters.

My YEPO 737A with recent 4.16.1-041601-lowlatency kernel under Mint 18.3

[Kernel-packages] [Bug 1708043] Re: Lenovo X1 Carbon Gen5 fails to resume

[Peter Bittner]

I have an X1 Carbon 6th Generation (Core i7 8th Gen, 16 GB RAM, 512 GB
SSD) and it behaves like described in the first comments above.

Specifically, when I close the notebook it somewhat goes in standby (or
not really, I'm not sure), the red dot blinks but underneath the
notebook gets hot within a few minutes. And sometimes, not always, it
freezes (or stays frozen) instead of waking up when I open the notebook
again.

I'm running 18.04 Bionic (development branch).

BTW, I _do_ realize that you want a starting point for bisection; I'm
sorry this is turning out so messy.

Title:
  Cryptoswap not working in Bionic

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Bionic:
  Confirmed

Bug description:
  I have cryptoswap set up both with the 2 GB default swap file and an 8
  GB swap partition with 8 GB of ram.  However, the system does not use
  this swap when it should.  For example, if I run a little test code
  which attempts to allocate 10 GB of memory in 1 GB chuncks, the system
  hangs with no obvious use of swap.  E.g. running top shows no swap use
  before the hang.  However, if I replace cryptoswap by standard swap,
  it works as expected: allocates the requested memory and exits, using
  swap.  Of course, my disk is slow, so this takes some time but it does
  work.

  I originally noticed this problem when compiling a very large
  application.  The system would hang on ld.  I've checked hardware
  using memtest and stress.  No problems.  This took me days to track
  down but I'm 99% certain now that the problem is with cryptoswap.  If
  I compile with cryptoswap: hang.  If I compile with standard swap: no
  problem.

Title:
  kernel 4.15 breaks nouveau on Lenovo P50

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After updating to linux 4.15.0-13-generic, the system freezes at boot,
  apparently when the nouveau driver tries to start.  The console is
  still in 80x25 text mode at this point.  No panic or error message is
  displayed, only unrelated log messages (screenshot attached).

  Booting in recovery mode is possible and allows X11 to start using the
  vesa driver.

  nouveau still works fine when booting an older kernel
  (4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

Re: [Kernel-packages] [Bug 1762468] Re: Cryptoswap not working in Bionic

[Martin D. Weinberg]

The first kernel on that list that exhibits the bug is the first one:
4.14 Final.  Recall: the bug results in a full up hang.  The disk stops
swapping (it's audible).   I can reboot with sysctl SUB however.

I then tested 4.13.0-36 from the Ubuntu 17.10 respoitory, followed by
4.11.12-041112-generic from mainline.  Both had the bug.

I also tested each of these without cryptswap (i.e. normal swap) and
they did not hang.  The system ground to a halt, but I could hear the
disk swapping and the process eventually completed.

I then booted an 16.04 live usb which has kernel 4.10.  I had to make a
cryptswap using cryptsetup on the swap partition of the hard disk, to
test it.   But this one worked! The behavior was a bit different that
more recent kernels: after allocating 6 GB of the 10 GB that I
requested, the system invoked the oom-killer on the process.  However,
it did not hang.

I then grabbed 4.10.1-041001-generic from mainline and tested it.  This
worked the same as the live usb.  So 4.10 does not have the bug,
although the oom-killer is invoked to kill the process grabbing the memory.

I have an older machine with an SSD.  This does not exhibit the bug on
Ubuntu 17.10 running 4.13.0-36.  However, this disk is _fast_ (Samsung
EVO), so I'm guessing that there is some tuning problem, maybe, in how
the kernel handles swap speed vs memory allocation requests???  I really
don't know.

After updating to linux 4.15.0-13-generic, the system freezes at boot,
apparently when the nouveau driver tries to start.  The console is still
in 80x25 text mode at this point.  No panic or error message is
displayed, only unrelated log messages (screenshot attached).

Booting in recovery mode is possible and allows X11 to start using the
vesa driver.

nouveau still works fine when booting an older kernel
(4.13.0-36-generic) so this problem seems to be specific to 4.15.0.

  System freezes when starting Xorg after installing linux-

Bug description:
  My laptop (Lenovo T440) freezes when starting Xorg (lightdm) only
  after installing the latest ubuntu kernel for 17.10, linux-
  image-4.13.0-32-generic.

  Am running Xorg instead of MIR due to MIR crashing when I initially
  upgraded from 17.04 to 17.10, but that's a different problem for a
  different day. It's been running with Xorg stably for at least 2-3
  months.

  If I boot with the previous kernel version on my /boot (linux-
  image-4.13.0-25-generic), everything works fine.

  If I boot with the latest mainline kernel from the Ubuntu mainline
  repo (4.15.0), everything works.

  Using grub's option to run "Recovery Mode" for the 4.13.0-32 kernel, I
  am able to use the CLI and access the encrypted root filesystem, which
  is how I generated the apport repo that's attached. It's only when
  telling it to continue Normal booting that it freezes, which is why I
  suspect the problem of being Xorg.

  When the system freezes, the fan starts to spin up. I cannot switch
  virtual consoles using CTRL-ALT-F{1-7}. CTRL-ALT-DEL pressed
  repeatedly doesn't do anything. To reboot, I have to hold the power
  button until the system powers off.

[Kernel-packages] [Bug 1756877] Re: Dell XPS 9530 (Nvidia GeForce GT 750M): Intermittent freeze when using nouveau

[Luke Carrier]

FYI I'm currently mitigating this using Bumblebee:

https://wiki.ubuntu.com/Bumblebee#Setup_for_14.04_and_later

I've not yet been able to get applications running against the discrete
chip, but since I'm now running with onboard Intel graphics the
stuttering is no longer an issue.

  Dell XPS 9530 (Nvidia GeForce GT 750M): Intermittent freeze when using
  nouveau

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I am on an Dell xps 9530 laptop and I had recently cleaned installed
  17.10. A few days back I decided to updated to 18.04 to check it out
  and report some bugs. The most annoying bug so far is the insane
  amount of input latency this update has brought with it to a degree
  that it makes it impossible to be productive. The issue is observable
  when using either the mouse or the keyboard. The mouse does not move
  immediately but it needs a second or two to register and start moving
  and even then at some point it freezes for half a second at some
  random point and then moves again. Also if I have two applications
  side by side and I try an move focus from one to the next at around
  the edges of each window the mouse freezes for a second and then
  moves. The keyboard freezes if it hasn't been used for a while and on
  the first keystroke will take a second to register and for a bonus you
  get the first keystorke repeated for around 15-30 times. So if you are
  trying to write "and" will become "aaand" or pressing
  "ctrl + T" in the browser will open not one but 20 tabs!

  I am reporting it here cause I am not sure what is causing all this
  latency (it could be libinput or something else entirely) but please
  try and fix this as soon as possible!!

[Kernel-packages] [Bug 1763170] [NEW] Bionic update to v4.16.1 stable release

[Seth Forshee]

Public bug reported:

SRU Justification

Impact:
   The upstream process for stable tree updates is quite similar
   in scope to the Ubuntu SRU process, e.g., each patch has to
   demonstrably fix a bug, and each patch is vetted by upstream
   by originating either directly from a mainline/stable Linux tree or
   a minimally backported form of that patch. The v4.16.1 upstream stable
   patch set is now available. It should be included in the Ubuntu
   kernel as well.

   git://git.kernel.org/

TEST CASE: TBD

   The following patches from the v4.16.1 stable release shall be
applied:

bitmap: fix memset optimization on big-endian systems
USB: serial: ftdi_sio: add RT Systems VX-8 cable
USB: serial: ftdi_sio: add support for Harman FirmwareHubEmulator
USB: serial: cp210x: add ELDAT Easywave RX09 id
serial: 8250: Add Nuvoton NPCM UART
mei: remove dev_err message on an unsupported ioctl
/dev/mem: Avoid overwriting "err" in read_mem()
media: usbtv: prevent double free in error case
parport_pc: Add support for WCH CH382L PCI-E single parallel port card.
crypto: lrw - Free rctx->ext with kzfree
crypto: ccp - Fill the result buffer only on digest, finup, and final ops
crypto: talitos - don't persistently map req_ctx->hw_context and req_ctx->buf
crypto: inside-secure - fix clock management
crypto: testmgr - Fix incorrect values in PKCS#1 test vector
crypto: talitos - fix IPsec cipher in length
crypto: ahash - Fix early termination in hash walk
crypto: caam - Fix null dereference at error path
crypto: ccp - return an actual key size from RSA max_size callback
crypto: arm,arm64 - Fix random regeneration of S_shipped
crypto: x86/cast5-avx - fix ECB encryption when long sg follows short one
Bluetooth: hci_bcm: Add 6 new ACPI HIDs
Btrfs: fix unexpected cow in run_delalloc_nocow
siox: fix possible buffer overflow in device_add_store
staging: comedi: ni_mio_common: ack ai fifo error interrupts.
Revert "base: arch_topology: fix section mismatch build warnings"
Input: ALPS - fix TrackStick detection on Thinkpad L570 and Latitude 7370
Input: i8042 - add Lenovo ThinkPad L460 to i8042 reset list
Input: i8042 - enable MUX on Sony VAIO VGN-CS series to fix touchpad
vt: change SGR 21 to follow the standards

[Kernel-packages] [Bug 1760851] Re: ethernet wired adapter lost

[Fabien COMBERNOUS]

After a second reboot, the wired adapter device reappeared.
And since this, it never disappeared again.

I suppose this bug could be closed.

[Kernel-packages] [Bug 1760654] Re: test_140_kernel_modules_not_tainted in kernel security test failed with 4.4 X-kvm

[Kamal Mostafa]

This seems to be a false failure caused by test script itself (qa-
regression-testing/scripts/test-kernel-security.py):

Here, test_140_kernel_modules_not_tainted is complaining about a module
'signpost' which is a test module that was inserted by an unrelated test
case (test_072_strict_devmem) which ran and failed earlier in this run
(see bug 1760649).  The fault is that test_072_strict_devmem fails to
remove its 'signpost' test module at line 768 if that assert at line 766
fails.

@Po-Hsu, could you take a look at fixing test_072_strict_devmem so that
it removes 'signpost' regardless of success or failure?

The following patches were added to the 5.48 version in Fedora and they
did fix the problem. Perhaps worth you adding them as well. Please see

Bug description:
  My laptop (Lenovo T440) freezes when starting Xorg (lightdm) only
  after installing the latest ubuntu kernel for 17.10, linux-
  image-4.13.0-32-generic.

  Am running Xorg instead of MIR due to MIR crashing when I initially
  upgraded from 17.04 to 17.10, but that's a different problem for a
  different day. It's been running with Xorg stably for at least 2-3
  months.

  If I boot with the previous kernel version on my /boot (linux-
  image-4.13.0-25-generic), everything works fine.

  If I boot with the latest mainline kernel from the Ubuntu mainline
  repo (4.15.0), everything works.

  Using grub's option to run "Recovery Mode" for the 4.13.0-32 kernel, I
  am able to use the CLI and access the encrypted root filesystem, which
  is how I generated the apport repo that's attached. It's only when
  telling it to continue Normal booting that it freezes, which is why I
  suspect the problem of being Xorg.

  When the system freezes, the fan starts to spin up. I cannot switch
  virtual consoles using CTRL-ALT-F{1-7}. CTRL-ALT-DEL pressed
  repeatedly doesn't do anything. To reboot, I have to hold the power
  button until the system powers off.

[Kernel-packages] [Bug 1763156] [NEW] Bluetooth doesn't reconnect to my headsetup post resume from sleep

[Anmar Oueja]

Public bug reported:

Steps to repro:

* Cold boot the laptop
* Pair it with bluetooth headset
* Listen to music
* Turn off the headset or turn off the bluetooth on the laptop
* Play music, sound comes out of the laptop speakers
* Turn on the headset back on or the bluetooth on the laptop
* Headset reconnects with the laptop and audio plays from the headset

-- all the above is expected --

* Suspend the laptop
* wait a minute or two for the headset to power down
* Resume the laptop
* Turn on the bluetooth headeset
* It doesn't automatically reconnect to the laptop (not expected behaviour)
* Launch Gnome Settings and select Bluetooth and force the headset to connect
* It connects for 2 seconds then disconnects (not expected behaviour)

The only to get the headset to reconnect again is by restarting the
bluetooth.service using systemctl.

[Kernel-packages] [Bug 1413440] Re: USB stops working after a while (xhci_hcd 0000:00:14.0: Timeout while waiting for setup device command)

[Sebastiaan Breedveld]

I can finally report a working solution for me.

Ubuntu 18.04 alpha
kernel 4.15.0-13-generic

Add these options to the GRUB command line:
pci=nomsi iommu=soft

USB works like a charm after resume :)

Bug description:
  On my laptop the kernel will sometimes drop the USB hub. After this,
  the laptop doesn't recognise any device plugged in to the USB ports -
  plugging and unplugging any device I've tried into any of the USB
  ports produces no response, not even dmesg entries.

  Strangely this also applies to bluetooth - it no longer works once USB
  has dropped (possibly the module is hung of the bus internally).

  Once this has happened only a reboot fixes it; I've not managed to
  find any combination of module unload/reload or suspend cycles to
  reinitialise things correctly.

[Kernel-packages] [Bug 1753430] Re: virtualbox-guest-utils.service not starting

[Tony Middleton]

Just did a fresh upgrade of Ubuntu Mate from Xenial to Bionic.  The
guest packages were installed on the Xenial system prior to upgrade.
During the upgrade the guest packages were upgraded, NOT removed.

However, on the upgraded system the virtualbox-guest-utils.service was
NOT started but could be started manually.

Thus the original bug reported on this number still applies, although
all the other issues found on the way seem to have been addressed.

Bug description:
  I am trialing various flavours of Ubuntu in Virtualbox virtual
  machines - Xubuntu, Lubuntu, Ubuntu and Ubuntu Mate.  All version
  18.04, running on Kubuntu 17.10 host.  All set up identically as far
  as I can tell, with virtualbox-guest-dkms, virtualbox-guest-utils and
  virtualbox-guest-x11 installed in each guest.

  All work fine except that shared folders does not work in 2 of the
  VMs.  It works in Xubuntu, Ubuntu but not in Lubuntu and Ubuntu Mate.
  On investigation it appears that the virtualbox-guest-utils.service is
  not started automatically on the two versions not working.  If I start
  it manually everything is OK.

  Here is the status -

Title:
  Significantly lower power and thermal limits on ThinkPad T480s (and
  probably others) than on Windows

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  A ThinkPad T480s under windows has a power limit of 44W, both short
  and long term, with a thermal maximum of about 93C or so. Under Linux,
  the power limits are 44W and 15W (short) or so, and the thermal limit
  is 80C, causing a significant performance loss.

  Looking at MSR and MCHBAR values, we can see that the values are
  correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

  $ sudo rdmsr -a 0x610
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  $ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
  0x0042816000dd8078

  
  Setting the MCHBAR to the same value as the MSR register solves the problem. 
At some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

  The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24
  -d 0x1a2 returns 20. Setting those bits to 7 increases it, resulting
  in performance comparative to Windows.

  Most of the analysis is based on the analysis in

  https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/

[Kernel-packages] [Bug 1763144] Re: Significantly lower power and thermal limits on ThinkPad T480s (and probably others) than on Windows

[Julian Andres Klode]

I have seen this problem on all bionic kernels I have tested. The
machine has never seen anything older than bionic. I installed it from a
daily end of March.

The mainline kernel does not fix the bug.

[Kernel-packages] [Bug 1763144] Re: Significantly lower power and thermal limits on ThinkPad T480s (and probably others) than on Windows

[Julian Andres Klode]

Note that the thermal limit seems to be rewritten by the EC at random
times.

The person originally discovering the issue wrote a userspace daemon to
write the proper stuff in memory from time to time -
https://github.com/erpalma/lenovo-throttling-fix - but this should best
get fixed in the kernel (unless it's a bug in the BIOS/EC firmware, then
it's out of our hands).

Title:
  Significantly lower power and thermal limits on ThinkPad T480s (and
  probably others) than on Windows

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  A ThinkPad T480s under windows has a power limit of 44W, both short
  and long term, with a thermal maximum of about 93C or so. Under Linux,
  the power limits are 44W and 15W (short) or so, and the thermal limit
  is 80C, causing a significant performance loss.

  Looking at MSR and MCHBAR values, we can see that the values are
  correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

  $ sudo rdmsr -a 0x610
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  $ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
  0x0042816000dd8078

  
  Setting the MCHBAR to the same value as the MSR register solves the problem. 
At some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

  The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24
  -d 0x1a2 returns 20. Setting those bits to 7 increases it, resulting
  in performance comparative to Windows.

  Most of the analysis is based on the analysis in

  https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/

Title:
  Kernel panic on a nfsroot system

Status in linux package in Ubuntu:
  Fix Committed
Status in linux source package in Artful:
  Confirmed

Bug description:
  == SRU Justification ==
  The following commit introduced a regression identified in bug 1734327:
  ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure management of 
the remaining blobs")

  The regression causes a kernel panic to occur after multiple TCP connection 
  creations/closures to the localhost.  The bug was found using STAF RPC calls, 
  but is easily reproducible with SSH.

  A revert of commit ac8f82a0b6d9 is needed to resolve this bug.  However, 
commit 4ae2508f0bed
  also needs to be reverted because it depend on commit ac8f82a0b6d9.

  == Fix ==
  Revert 4ae2508f0bed ("UBUNTU: SAUCE: LSM stacking: add stacking support to 
apparmor network hooks")
  Revert ac8f82a0b6d9 ("UBUNTU: SAUCE: LSM stacking: LSM: Infrastructure 
management of the remaining blobs")

  == Test Case ==
  A test kernel was built with these two commits reverted and tested by the 
original bug reporter.
  The bug reporter states the test kernel resolved the bug.



  
  == Original Bug Description ==
  Summary:
  Kernel panic occurs after multiple TCP connection creations/closures to the 
localhost.
  The bug was found using STAF RPC calls, but is easily reproducible with SSH.
  The bug doesn't appear on an identical virtual machine booting from the disk.
  The bug is not reproducible on a similarly-prepared Ubuntu 16.04 machine.
  The bug is reproducible using an older 4.13.0-16-generic kernel
  Reproducible on multiple hardware types.
  Unable to create a kernel memory dump due to makedumpfile errors.
  apport-bug save attached.

  NFSRoot boot options:
  vmlinuz initrd=initrd.img boot=nfs root=/dev/nfs 
nfsroot=190.0.0.254:/diskless/host/u1616/Ubuntu/17.10 intel_iommu=on 
net.ifnames=0 biosdevname=0 apparmor=0 ip=:eth0:dhcp

  Software:
  OS: Ubuntu 17.10
  Kernel: 4.13.0-17-generic x86_64

  Reproduction steps:
  1. Boot a system from a nfsroot
  2. Configure password-less localhost ssh access
  3. Run a loop: `while true; do ssh localhost 'uname -a'; done`
  4. Wait for system to crash

  As is the case for bionic, linux-kvm requires UNWINDER_FRAME_POINTER

  Author: Seth Forshee 
  Date:   Sat Dec 9 22:08:25 2017 -0600

  UBUNTU: [Config] CONFIG_UNWINDER_FRAME_POINTER=y for amd64
  
  During the rebase to 4.15 UNWINDER_ORC was chosen as the stack
  unwinder as it promises a 5-10% performance improvement over
  using UNWINDER_FRAME_POINTER. However it turns out to have a
  couple of downsides. It adds a new requierment for building dkms
  modules, and it does not produce the reliable stack traces
  required for livepatch. Switch back to UNWINDER_FRAME_POINTER.

Title:
  Significantly lower power and thermal limits on ThinkPad T480s (and
  probably others) than on Windows

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  A ThinkPad T480s under windows has a power limit of 44W, both short
  and long term, with a thermal maximum of about 93C or so. Under Linux,
  the power limits are 44W and 15W (short) or so, and the thermal limit
  is 80C, causing a significant performance loss.

  Looking at MSR and MCHBAR values, we can see that the values are
  correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

  $ sudo rdmsr -a 0x610
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  $ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
  0x0042816000dd8078

  
  Setting the MCHBAR to the same value as the MSR register solves the problem. 
At some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

  The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24
  -d 0x1a2 returns 20. Setting those bits to 7 increases it, resulting
  in performance comparative to Windows.

  Most of the analysis is based on the analysis in

  https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/

[Kernel-packages] [Bug 1763144] Re: Significantly lower power and thermal limits on ThinkPad T480s (and probably others) than on Windows

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  Significantly lower power and thermal limits on ThinkPad T480s (and
  probably others) than on Windows

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  A ThinkPad T480s under windows has a power limit of 44W, both short
  and long term, with a thermal maximum of about 93C or so. Under Linux,
  the power limits are 44W and 15W (short) or so, and the thermal limit
  is 80C, causing a significant performance loss.

  Looking at MSR and MCHBAR values, we can see that the values are
  correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

  $ sudo rdmsr -a 0x610
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  $ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
  0x0042816000dd8078

  
  Setting the MCHBAR to the same value as the MSR register solves the problem. 
At some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

  The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24
  -d 0x1a2 returns 20. Setting those bits to 7 increases it, resulting
  in performance comparative to Windows.

  Most of the analysis is based on the analysis in

  https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/

Title:
  Significantly lower power and thermal limits on ThinkPad T480s (and
  probably others) than on Windows

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  A ThinkPad T480s under windows has a power limit of 44W, both short
  and long term, with a thermal maximum of about 93C or so. Under Linux,
  the power limits are 44W and 15W (short) or so, and the thermal limit
  is 80C, causing a significant performance loss.

  Looking at MSR and MCHBAR values, we can see that the values are
  correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

  $ sudo rdmsr -a 0x610
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  42816000dd8160
  $ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
  0x0042816000dd8078

  
  Setting the MCHBAR to the same value as the MSR register solves the problem. 
At some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

  The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24
  -d 0x1a2 returns 20. Setting those bits to 7 increases it, resulting
  in performance comparative to Windows.

  Most of the analysis is based on the analysis in

  https://www.reddit.com/r/thinkpad/comments/870u0a/t480s_linux_throttling_bug/

  This applies to all bionic kernels I have tested so far, including

[Kernel-packages] [Bug 1763144] [NEW] Significantly lower power and thermal limits on ThinkPad T480s (and probably others) than on Windows

[Julian Andres Klode]

Public bug reported:

A ThinkPad T480s under windows has a power limit of 44W, both short and
long term, with a thermal maximum of about 93C or so. Under Linux, the
power limits are 44W and 15W (short) or so, and the thermal limit is
80C, causing a significant performance loss.

Looking at MSR and MCHBAR values, we can see that the values are
correctly at 44W in the MSR, but the MCHBAR is set to a lower value:

$ sudo rdmsr -a 0x610
42816000dd8160
42816000dd8160
42816000dd8160
42816000dd8160
42816000dd8160
42816000dd8160
42816000dd8160
42816000dd8160
$ sudo /home/jak/Downloads/iotools-1.5/iotools mmio_read64 0xfed159a0
0x0042816000dd8078


Setting the MCHBAR to the same value as the MSR register solves the problem. At 
some point intel-rapl seems to reduce overall frequency to 600 MHz, though.

The thermal limit is configured in MSR register 0x1a2; rdmsr -f 29:24 -d
0x1a2 returns 20. Setting those bits to 7 increases it, resulting in
performance comparative to Windows.

Most of the analysis is based on the analysis in

Bug description:
  Kernel config 4.15.0-13-generic #14 (and same for 4.15.0-15-generic)
  is not OK, because both security mechanisms nobp AND expoline are
  enabled:

  CONFIG_KERNEL_NOBP=y
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  # CONFIG_EXPOLINE_MEDIUM is not set
  CONFIG_EXPOLINE_FULL=y

  If the kernel is compiled with a gcc that can generate expoline thunks
  the correct config is as follows:

  # CONFIG_KERNEL_NOBP is not set
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  # CONFIG_EXPOLINE_MEDIUM is not set
  CONFIG_EXPOLINE_FULL=y

  Alternatively the auto-detection patch can be used which is upstream
  as of today:

  commit 6e179d64126b909f0b288fa63cdbf07c531e9b1d

  s390: add automatic detection of the spectre defense
  
  Automatically decide between nobp vs. expolines if the spectre_v2=auto
  kernel parameter is specified or CONFIG_EXPOLINE_AUTO=y is set.
  
  The decision made at boot time due to CONFIG_EXPOLINE_AUTO=y being set
  can be overruled with the nobp, nospec and spectre_v2 kernel parameters.
  
  If this patch is used, then the correct config is

  # CONFIG_KERNEL_NOBP is not set
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  CONFIG_EXPOLINE_AUTO=y
  # CONFIG_EXPOLINE_FULL is not set

  This patch goes together with three others, so a total of four patches
  would be needed for the latest-and-greated solution:

  b2e2f43a01bace1a25bdbae04c9f9846882b727a

[Kernel-packages] [Bug 1763107] [NEW] linux-kvm 4.15 needs UNWINDER_FRAME_POINTER

[Kamal Mostafa]

Public bug reported:

As is the case for bionic, linux-kvm requires UNWINDER_FRAME_POINTER vs
UNWINDER_ORC:

UBUNTU: [Config] CONFIG_UNWINDER_FRAME_POINTER=y for amd64

During the rebase to 4.15 UNWINDER_ORC was chosen as the stack
unwinder as it promises a 5-10% performance improvement over
using UNWINDER_FRAME_POINTER. However it turns out to have a
couple of downsides. It adds a new requierment for building dkms
modules, and it does not produce the reliable stack traces
required for livepatch. Switch back to UNWINDER_FRAME_POINTER.

[Kernel-packages] [Bug 1762913] Re: [OPAL] Assert fail: core/mem_region.c:447:lock_held_by_me(>free_list_lock)

[Joseph Salisbury]

The Bionic request has been sent.  However, because Artful is a stable
release, it requires testing before submitting a SRU request.

I built an Artful test kernel with commit 
47712a921bb781caf69fca9eae43be19968816cb.  The test kernel can be downloaded 
from:
http://kernel.ubuntu.com/~jsalisbury/lp1762913

Can you test this kernel and see if it resolves this bug?

Note, to test this kernel, you need to install both the linux-image and
linux-image-extra .deb packages.

Thanks in advance!

  Subject: [PATCH] powerpc/watchdog: remove arch_trigger_cpumask_backtrace

  The powerpc NMI IPIs may not be recoverable if they are taken in
  some sections of code, and also there have been and still are issues
  with taking NMIs (in KVM guest code, in firmware, etc) which makes them
  a bit dangerous to use.

  Generic code like softlockup detector and rcu stall detectors really
  hammer on trigger_*_backtrace, which has lead to further problems
  because we've implemented it with the NMI.

  So stop providing NMI backtraces for now. Importantly, the powerpc code
  uses NMI IPIs in crash/debug, and the SMP hardlockup watchdog. So if the
  softlockup and rcu hang detection traces are not being printed because
  the CPU is stuck with interrupts off, then the hard lockup watchdog
  should get it with the NMI IPI.

  Fixes: 2104180a5369 ("powerpc/64s: implement arch-specific hardlockup 
watchdog")

[Kernel-packages] [Bug 1762844] Re: ISST-LTE:KVM:Ubuntu1804:BostonLC:boslcp3: Host crashed & enters into xmon after moving to 4.15.0-15.16 kernel

[Joseph Salisbury]

Can you see if the bug happens with and of these mainline kernels?  We
can perform a kernel bisect if we can narrow down to the last good
kernel version and first bad one:

v4.14 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.14/
v4.15-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc1/
v4.15-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15-rc4/
v4.15 Final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15/

You don't have to test every kernel, just up until the kernel that first
has this bug.

Thanks in advance!

[Kernel-packages] [Bug 1762816] Re: chaoskey interferes with suspend on thinkpad

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

Title:
  chaoskey interferes with suspend on thinkpad

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Thinkpad T450s, docking station, Altus Metrum Chaoskey plugged into
  the docking station - suspend fails often (more than half the time,
  maybe not 100% but easily duplicated in my setup) in that it doesn't
  seem to go all the way down - and on wakeup, lsusb output doesn't
  update, `lsusb -t` hangs when run.  It *may* require "suspend, undock,
  unsuspend" but I'm not convinced...

  Interesting logs include a "blocked for more than 120 seconds"
  traceback after restore that goes through chaoskey_disconnect even
  though the laptop is undocked so it's no longer attached:

  Kernel is most recently `4.15.0-13-generic #14-Ubuntu` but it's been
  going on for the last month of bionic, and *possibly* longer but I
  only recently caught that the Chaoskey was related.

[Kernel-packages] [Bug 1762719] Comment bridged from LTC Bugzilla

--- Comment From martin.schwidef...@de.ibm.com 2018-04-11 12:11 EDT---
> Cherry picked the auto-detection patches into bionic, set
> CONFIG_EXPOLINE_AUTO=y and CONFIG_KERNEL_NOBP=n.

You sure are quick.. Unfortunately there is a bug in the auto-detection
which is solved by a patch I created today. It can be found on the
s390/linux:features branch on kernel.org:

https://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git/commit/?h=features=6a3d1e81a434fc311f224b8be77258bafc18ccc6

I plan to send a please-pull for this by the end of the week.

Title:
  System Z {kernel} UBUNTU18.04 wrong kernel config

Status in Ubuntu on IBM z Systems:
  Fix Committed
Status in linux package in Ubuntu:
  Fix Committed

Bug description:
  Kernel config 4.15.0-13-generic #14 (and same for 4.15.0-15-generic)
  is not OK, because both security mechanisms nobp AND expoline are
  enabled:

  CONFIG_KERNEL_NOBP=y
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  # CONFIG_EXPOLINE_MEDIUM is not set
  CONFIG_EXPOLINE_FULL=y

  If the kernel is compiled with a gcc that can generate expoline thunks
  the correct config is as follows:

  # CONFIG_KERNEL_NOBP is not set
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  # CONFIG_EXPOLINE_MEDIUM is not set
  CONFIG_EXPOLINE_FULL=y

  Alternatively the auto-detection patch can be used which is upstream
  as of today:

  commit 6e179d64126b909f0b288fa63cdbf07c531e9b1d

  s390: add automatic detection of the spectre defense
  
  Automatically decide between nobp vs. expolines if the spectre_v2=auto
  kernel parameter is specified or CONFIG_EXPOLINE_AUTO=y is set.
  
  The decision made at boot time due to CONFIG_EXPOLINE_AUTO=y being set
  can be overruled with the nobp, nospec and spectre_v2 kernel parameters.
  
  If this patch is used, then the correct config is

  # CONFIG_KERNEL_NOBP is not set
  CONFIG_EXPOLINE=y
  # CONFIG_EXPOLINE_OFF is not set
  CONFIG_EXPOLINE_AUTO=y
  # CONFIG_EXPOLINE_FULL is not set

  This patch goes together with three others, so a total of four patches
  would be needed for the latest-and-greated solution:

  b2e2f43a01bace1a25bdbae04c9f9846882b727a

Title:
  Cpu utilization showing system time for kvm guests (performance)

Status in The Ubuntu-power-systems project:
  Fix Committed
Status in linux package in Ubuntu:

Bug description:
  == SRU Justification ==
  All KVM guest cpu utilization is being reported as sys% time in the host.
  It turns out Guest time accounting (CONFIG_VIRT_CPU_ACCOUNTING_GEN) has
  been broken since v4.13 by commit 8b24e69fc47e436.

  Commit 61bd0f66ff92 fixes this bug and is included in mainline as of 
v4.16-rc5.
  The commit was cc'd to upstream stable, but has not yet landed in upstream 
4.15.

  == Fix ==
  61bd0f66ff92 ("KVM: PPC: Book3S HV: Fix guest time accounting with 
VIRT_CPU_ACCOUNTING_GEN")

  == Regression Potential ==
  Low.  Also cc'd to stable, so it has had additionl upstream review.  Limited 
to powerpc.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.

  Subject: [PATCH] powerpc/watchdog: remove arch_trigger_cpumask_backtrace

  The powerpc NMI IPIs may not be recoverable if they are taken in
  some sections of code, and also there have been and still are issues
  with taking NMIs (in KVM guest code, in firmware, etc) which makes them
  a bit dangerous to use.

  Generic code like softlockup detector and rcu stall detectors really
  hammer on trigger_*_backtrace, which has lead to further problems
  because we've implemented it with the NMI.

  So stop providing NMI backtraces for now. Importantly, the powerpc code
  uses NMI IPIs in crash/debug, and the SMP hardlockup watchdog. So if the
  softlockup and rcu hang detection traces are not being printed because
  the CPU is stuck with interrupts off, then the hard lockup watchdog
  should get it with the NMI IPI.

watchdog")

But I will let it running anyway since I'm not sure if it affects to the

Title:
  [i40e] LACP bonding start up race conditions

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Triaged

Bug description:
  When provisioning Ubuntu servers with MAAS at once, some bonding pairs
  will have unexpected LACP status such as "Expired". It randomly
  happens at each provisioning with the default xenial kernel(4.4), but
  not reproducible with HWE kernel(4.13). I'm using Intel X710 cards
  (Dell-branded).

  Using the HWE kernel works as a workaround for short term, but it's
  not ideal since 4.13 is not covered by Canonical Livepatch service.

  How to reproduce:
  1. configure LACP bonding with MAAS
  2. provision machines
  3. check the bonding status in /proc/net/bonding/bond*

  frequency of occurrence:
  About 5 bond pairs in 22 pairs at each provisioning.

[Kernel-packages] [Bug 1762986] Re: Display resolution of monitor via HDMI incorrectly identified

[Joseph Salisbury]

Did this issue start happening after an update/upgrade?  Was there a
prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.16 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

  Display resolution of monitor via HDMI incorrectly identified

Status in linux package in Ubuntu:

Bug description:
  I use a Philips BDM4037U 40'', 4k monitor.
  Connecting it via DP to my Lenovo 910 4k does work (except for random display 
blackouts).

  But when connecting it via HDMI the display resolution is sometimes
  correctly set (I cannot see a pattern when this works) but sometimes
  the display resolution is just set to FullHD, 1920x1080 Pixel @ 60Hz.

  Due to limitations of the supported HDMI protocol on my laptop I can
  only drive the display with 30Hz when in 4k mode. Which is totally
  fine for me. But this mode isn't correctly identified, most of the
  time.

Title:
  Display Port issues - screen blackouts

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I use a Philips BDM4037U 40'', 4k monitor.
  Connecting it via DP to my Lenovo 910 4k gives me random blackouts.

  It appears to me that this mostly happens after some time of work,
  also more likely when the CPU has to handle more than average load,
  sooner in 30Hz than in 60Hz mode. But it happens for sure after some
  time, each day.

  I was unsure if this is a problem with the monitor itself (although when 
connected via HDMI this isn't an issue).
  I found similar bug reports for Windows, where it was suggested to update the 
firmware.
  My laptop has updated everything - a current BIOS (which dates back to June 
2017 or so), updated Windows, latest Ubuntu.
  The same problem existed in 17.10, with x-org and Wayland sessions.

  Note, there is another issue with this monitor filed by me, but
  unrelated AFAIK:

  Very inaccurate TSC clocksource on HP ProLiant DL380 Gen10 with kernel

Bug description:
  On kernel 4.13.0-37-generic, HP ProLiant DL380 Gen10 systems have been
  observed with very large clock offsets, as measured by NTP.  Over the
  past few days on one of our production systems, we've used 3 different
  kernels: https://pastebin.ubuntu.com/p/nDkkgRqdtv/

  All of these kernels default to the TSC clocksource, which is supposed
  to be very reliable on Skylake-X CPUs.  On 4.4 (linux-image-generic-
  lts-xenial) it works as expected; on 3.13 (trusty default kernel) it
  works a little worse, and on 4.13 (linux-image-generic-hwe-16.04) it
  is much worse.  Today I switched 4.13 from the TSC clocksource to the
  HPET clocksource and it improved the situation dramatically.

  I've produced loopstats & peerstats graphs from NTP corresponding to
  the dates in the pastebin above and placed them at
  https://people.canonical.com/~paulgear/ntp/.
