[Kernel-packages] [Bug 1754551] Re: Kernel 3.13.0-143 breaks multi-monitor support

[Arthur Shagall]

This may take a while. I'll need to find half a day to fiddle with this.
However, here's an interesting note. When booting with the 3.13.0-143
kernel, the NVIDIA X Server Settings applet didn't display any of the X
server info. Uninstalling the NVIDIA driver didn't fix things; the
second screen still wasn't detected.

[Pragnesh Sampat]

I was about to give up trying to recreate this.  Everything was updated
as a hour or so earlier today.  Meaning in the last 5 days, whatever
updates were prompted had been applied as and when they showed up and I
got around to doing the updates.  System had not been restarted since
the time below.  It had been up for over 5 days now since the last time
it froze.

Title:
  AMD 7 1800X system (Dell Inspiron 5675) randomly freezes

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  This is happening every day or so.  I cannot see anything in the
  kern.log or syslog that give me a clue on where/what the issue might.
  I was using Ubuntu 17.10 earlier and upgraded to Ubuntu 18.04 on
  3/3/2018, since I thought kernel 4.15 might have better support for
  the ryzen 7 and also maybe amdgpu for the radeon 580 might be newer.
  I have removed most external devices except for networking and HDMI
  and audio out.

  Attached a tarball of info, although I believe that since I used
  'ubuntu-bug linux' command, the information might be duplicated,
  apologize for any extra attachments.

  iwlwifi regression in artful - intermittent total packet loss

Status in linux package in Ubuntu:
  Expired

Bug description:
  Recently I have been experiencing intermitted total packet loss over
  wifi.

  I've already been looking at another issue in which Bluetooth
  coexistence seems to be causing controller hardware to crash - bug
  1719210 - so I'm rather suspicious of the updated iwlwifi microcode
  that is used by newer kernel versions.

  Unfortunately, I don't have a good reproduction recipe, as the fault
  doesn't seem to occur immediately after boot, nor is it an absolute
  failure of connectivity - from a user perspective, it feels like, for
  example, the website you are using is responding exceptionally slowly.
  It is only on testing multiple remote sites, and finding that
  rebooting into an earlier kernel fixes the issue, that it is apparent
  that it's a local OS problem.

[Kernel-packages] [Bug 1746340] Re: Samsung SSD corruption (fsck needed)

[Lucas Zanella]

Sorry I didn't test it yet. I had to travel and use the computer so I
did a fsck on onvme0n1p2 only, to get it working.

I thought fsck /dev/nvme0n1p2 was the same a fscking the rootfs. I do it
every time the error happens. I didn't understand exactly what you
meant.

Also I think NVME_QUIRK_NO_DEEPEST_PS had no effect when added. I'd
however try to make it work with it first, and if everything goes ok I'd
take it off to see if it continues.

If I need to do it before the error happens, I can just run my live
ubuntu and do it.

Thank you for your help.

  Ubuntu 4.13.0-21.24-generic 4.13.13

  
  I have a Razer Blade Stealth 2016. The first Ubuntu I installed was Ubuntu 
17.04, which gave me this error after 2 weeks of usage. After that, I installed 
16.04 and used it for MONTHS without any problems, until it produced the same 
error this week. I think it has to do with the ubuntu updates, because I did 
one recently and one today, just before this problem. Could be a coincidence 
though.

  I notice the error when I try to save something on disk and it says me
  that the disk is in read-only mode:

  Rebooting the ubuntu will give me a black terminal where I can run
  fsck /dev/nvm30n1p2 (something like that) and it fill fix a lot of
  orphaned inodes. The majority of time it boots back to the Ubuntu
  working good, but some times it boots to a broken ubuntu (no images,
  lots of things broken). I have to reinstall ubuntu then.

  Every time I reinstall my Ubuntu, I have to try lots of times until it
  installs without an Input/Output error. When it installs, I can use it
  for some hours without having the problem, but if I run the software
  updates, it ALWAYS crashes and enters in read-only mode, specifically
  in the part that is installing kernel updates.

  I noticed that Ubuntu installs updates automatically when they're for
  security reasons. Could this be the reason my Ubuntu worked for months
  without the problem, but then an update was applied and it broke?

  I thought that this bug was happening:
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1678184 and tried
  different nvme_core.default_ps_max_latency_us= combinations, all them
  gave errors. I just changed to 0 and I had no error while using ubuntu
  (however I didn't test for a long time) but I still had the error
  after trying to update my ubuntu.

  My Samsung 512gb SSD is:

  SAMSUNG MZVLW512HMJP-0, FW REV: CXY7501Q

  on a Razer Blade Stealth.

  I also asked this on ask ubuntu, without success:
  https://askubuntu.com/questions/998471/razer-blade-stealth-disk-
  corruption-fsck-needed-probably-samsung-ssd-bug-afte

  Please help me, as I need this computer to work on lots of things :c

  Ever since I updated my computer later last week I have had no

  response to these ping commands:

  $ ping google.ca

  $ ping 8.8.8.8
  PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

  localhost works, and I am still able to login to my router over
  wireless. No other computer or phone in my house has any problem with
  the internet, so the problem is specific only to my computer and only
  after the software update.

  the nm-applet is alive and I am able to see the wireless connections
  available to me. If I reconnect to the wifi connection it makes no
  difference.

  If I run "sudo service network-manager restart" it also makes no
  difference.

  The only solution I have found so far to fix the problem is to
  completely restart the computer.

  Any help or advice would be appreciated. If I missed some valuable
  information let me know and I will come back with more info.

[Kernel-packages] [Bug 1662316] Re: Asus GL553VE laptop keyboard backlight uncontrollable and Fn keys not working

[ROnaldve]

Adding 'acpi_osi=' to /etc/default/grub solves it all for me, on an old
Dell laptop, an old Compaq nx7400 and a quite new HP G2.  This seem to
fool the bios to think its a Windows OS.

Doing a 'sudo update-initramfs -u' and ' sudo update-grub' and a reboot
makes it complete.

This back-light issue obviously happened back in 2008 .. old bug  ;-)

[Kernel-packages] [Bug 1754592] Re: Xenial update to 4.4.114 stable release

[Stefan Bader]

** Description changed:

+ SRU Justification
  
- 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 4.4.114 upstream stable
+    patch set is now available. It should be included in the Ubuntu
+    kernel as well.

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.

  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 4.4.114 upstream stable
 patch set is now available. It should be included in the Ubuntu
 kernel as well.

  TEST CASE: TBD

 The following patches from the 4.4.114 stable release shall be
  applied:

Bug description:
  [Impact]
  After upgrading an Ubuntu/arm64 KVM host past xenial, your xenial-based 
guests will fail to boot.

  [Test Case]
  Boot a xenial cloud image with qemu-efi-aarch64 from artful/bionic.

  [Regression Risk]
  I've tested booting a xenial cloud image in bionic (ACPI mode), and 
regression tested w/ xenial's qemu-efi (DTB mode). I've regression tested on a 
Cavium ThunderX CRB1S, Caviumt ThunderX CRB2S and an APM X-Gene 2 Merlin board.

  Patches 1-5 change only code in the GICv3 driver. The xenial GA kernel
  only supported 2 GICv3 systems - the 1 socket and 2 socket variants of
  the Cavium ThunderX CRB - and I've regression tested on those systems.

  Patch 6 only adds new macro definitions.

  Patch 7 is restricted to devicetree code, except for a change to
  earlycon.c:param_setup_earlycon(). In the case that 'earlycon' is
  passed on the cmdline (vs. earlycon=something), this function used to
  return 0 - but now it will return -ENODEV on non-devicetree systems,
  which is a subtle API change. However, according to kernel-
  parameters.txt (and the code itself), 'earlycon' by itself is only
  valid on devicetree systems. Just to be sure, I booted an x86 system
  up w/ 'earlycon' with and without this series, and observed no
  difference.

  Patch 8 adds the SPCR table parser, but no caller to it yet. It also
  modifies the same earlycon code as Patch 7 - here it avoids earlycon
  init in the case that the devicetree-specific 'earlycon' was passed.
  As mentioned in my analysis Patch 7, this codepath is only supported
  for devicetree systems, and has been regression tested on x86.

  Patch 9 turns on CONFIG_ACPI_SPCR_TABLE - however, this driver will
  only be built for arm64. TBH, I'm not 100% sure how Kconfig knows not
  to build this for other archs - but I checked the logs, and there's no
  spcr.o built on other archs. (Not that that should be a problem - they
  would just grow a bit of unused code).

  Patch 10 only touches arm64-specific code, adding the call to
  parse_spcr(), so risk is limited to arm64.

  Patch 11 adds a new match method to the ARM-specific pl011 console
  driver, so regression risk to other architectures is negligible.

[Kernel-packages] [Bug 1750937] Re: 4.4.0-116 Kernel update on 2/21 breaks Nvidia drivers (on 14.04 and 16.04) by an insufficient compiler!

[Filippo Molesti]

Could we please know when this bug is going to be fixed at last?

If is not uncommon, actually quite common I would say, to have a NVIDIA
graphic card and a more recent version of GCC installed than the one in
the Ubuntu distribution, which is quite old. And then the machine is
broke when the new kernel is installed!

All the fixes in the above risk breaking the machine irreparably. Even
reinstalling Ubuntu from scratch may not work in the long run, if the
bug is not fixed in the new kernel version, because one also need to use
the most recent versions of GCC and thus the problem is bound to
reoccur. And having to keep using kernel 112 also looks quite
unsatisfactorily as a long term solution.

We need the matter to be fixed once and for all.

  Running fine with nvidia-384 until this kernel update came along.
  When booted into the new kernel, got super low resolution and nvidia-
  settings was missing most of its functionality - could not change
  resolution.

  Rebooted into 4.4.0-112 kernel and all was well.

  The root cause of the problem has been found to be installing the -116
  kernel without a sufficiently updated version of gcc.  In my case, my
  system received the gcc update AFTER the kernel update.

  Uninstalling the -116 kernel and reinstalling it with the updated
  version of gcc solved the problem for me.

Title:
  System freezes on copy to USB drive since kernel 4.13.0-36 (32bit)

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Lately one of my boxes reproducably freezes when I copy data from
  internal hard disk to an USB device (USB hard disk or USB key). It
  looks like it works at first, than the "wait for IO load" in the
  system monitor applet rises to max and the system does no longer
  respond to input, only hard reboot brings it back to life.

  When booting the previous kernel 4.13.0-32 all is fine. Do I boot to
  -36 the error is back.

  I append a lshw dump as text file.
  The hardware basically:
   ASRock Board D1800B-ITX
   CPU: Intel(R) Celeron(R) CPU  J1800  @ 2.41GHz
    4GB RAM
    otherwise nothing special

I don't think so; how we're using/clearing/stopping bcache has changed.
I can reproduce this on multiple trusty kernels:

3.13.0-101-generic (buildd@lgw01-40) #148-Ubuntu SMP Thu Oct 20
22:08:32 UTC 2016
3.13.0-107-generic (buildd@lcy01-09) #154-Ubuntu SMP Tue Dec 20

I can confirm that newer kernels do not have this issue:

4.4.0-116-generic (buildd@lcy01-amd64-023) (gcc version 4.8.4 (Ubuntu
4.8.4-2ubuntu1~14.04.4))

Xenial, Artful and Bionic are fine.

[Kernel-packages] [Bug 1753428] Re: nobp enable msg during boot

[Frank Heimes]

The above mentioned kernel ring buffer message - as well as further related 
Kernel Parameters for mitigation control - is documented here:
https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown/MitigationControls
at the 'Mitigation Controls' page - for all architectures, incl. s390x, as 
agreed upon.

The above msg is created for informative purposes.
As you already pointed out there are alternative ways to get the status of a 
specific setting.
Hence we think that this msg doesn't harm in general, but can be discussed.

[Kernel-packages] [Bug 1754571] Re: Desktop system won't run with latest kernel 4.13 36/40

[Joseph Salisbury]

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.

[Kernel-packages] [Bug 1366418] Re: Bluetooth BCM43142A0 doesn’t work

  Bluetooth BCM43142A0 doesn’t work

Status in bluez package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Fix Committed
Status in linux-firmware package in Ubuntu:
  Incomplete

Bug description:
  I’ve installed ubuntu 14.04 and my computer’s builtin bluetooth
  (computer is an Asus x550ln) doesn’t work at all. Bluetooth is not
  displayed in the menu bar, if I open the bluetooth UI and switch on,
  nothing happens and the result of “hcitool dev” is empty.

  I have tried to install the windows driver with ndiswrapper, and the
  bluetooth device seems to be detected as an usb bluetooth device but
  still not working. I then add the device to the bluetooth usb device
  and was able to activate bluetooth in the UI but it does not detect
  any other devices (I’ve tested with a smartphone).

  The driver I have installed can be found in asus page =>
  http://www.asus.com/fr/Notebooks_Ultrabooks/X550LN/HelpDesk_Download/
  Select Windows OS, then “bluetooth” section, take the Broadcom driver
  (should be the first one).

  If you extract this archive, you will find a file named “bcbtums-
  win8x64-brcm.inf” which I installed using the following command:

  ndiswrapper -i bcbtums-win8x64-brcm.inf

  Then, the result of “ndiswrapper -l” is:

  bcbtums-win8x64-brcm : driver installed
device (04CA:2006) present

  in usb-devices, I find a device which was not present before
  installation (I might have activated btusb before on this paste):

  T:  Bus=02 Lev=01 Prnt=01 Port=05 Cnt=02 Dev#=  3 Spd=12  MxCh= 0
  D:  Ver= 2.00 Cls=ff(vend.) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
  P:  Vendor=04ca ProdID=2006 Rev=01.12
  S:  Manufacturer=Broadcom Corp
  S:  Product=BCM43142A0
  S:  SerialNumber=B8EE6593D989
  C:  #Ifs= 4 Cfg#= 1 Atr=e0 MxPwr=0mA
  I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=01 Driver=btusb

  I:  If#= 3 Alt= 0 #EPs= 0 Cls=fe(app. ) Sub=01 Prot=01 Driver=(none)

  then, “echo "04ca 2006" > /sys/bus/usb/drivers/btusb/new_id”, and I
  can switch usb on, but no device will be detected and I’ve found this
  in the dmesg:

  [2200.843126] Bluetooth: hci0 command 0x1003 tx timeout

  which looks pretty much like a “bluetooth not working” message which I
  don’t understand in details.

  I leave here my full dmesg:

[Kernel-packages] [Bug 1754592] Re: Xenial update to 4.4.114 stable release

[Stefan Bader]

Deliberately skipping "Revert "module: Add retpoline tag to VERMAGIC""
because we decided we actually are fine with flagging things that way.

Skipping because already applied:
* Slow system response time due to a monitor bug (bug 1606147)
  - x86/cpu/intel: Introduce macros for Intel family numbers
* CVE-2017-1000364
  - mm/mmap.c: do not blow on PROT_NONE MAP_FIXED holes in the stack
* CVE-2017-17448
  - netfilter: nfnetlink_cthelper: Add missing permission checks
* CVE-2017-17450
  - netfilter: xt_osf: Add missing permission checks

We backported the following set for (bug 16407868):
 * netfilter: x_tables: pass xt_counters struct instead of packet
   counter
 * netfilter: x_tables: pass xt_counters struct to counter allocator
 * netfilter: x_tables: pack percpu counter allocations
this caused the following stable patch to be not needed in Xenial:
 * netfilter: fix IS_ERR_VALUE usage

Skipped until later decision (Spectre v2 upstream):
* x86/retpoline: Fill RSB on context switch for affected CPUs
  -> re-defines the SPEC_CTRL bit with a different name and does
 some STUFF_RSB related things

  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 4.4.114 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 4.4.114 stable release shall be
  applied:

If i remember correct then from 4.15 the retpoline fixes are used for
spectre mitigation so the noibpb code is not used.

[Kernel-packages] [Bug 1754621] Re: Builtin touchpad is not seen in 'DELL Latitude E5550' after the reboot during update.

[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.

  After an unexpected reboot, cursor disappeared. The only thing, which
  helped -- typing

  gsettings set org.gnome.settings-daemon.plugins.cursor active false

  and rebooting again. However, cursor now doesn't move with a touchpad.
  I have found this https://wiki.ubuntu.com/DebuggingTouchpadDetection.
  I have checked, if cursor moves with a mouse and it does. And there's
  no touchpad in /proc/bus/input/devices. So, I was recommended there to
  put it here as a bug.

Title:
  Builtin touchpad is not seen in 'DELL Latitude E5550' after the reboot
  during update.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  After an unexpected reboot, cursor disappeared. The only thing, which
  helped -- typing

  gsettings set org.gnome.settings-daemon.plugins.cursor active false

  and rebooting again. However, cursor now doesn't move with a touchpad.
  I have found this https://wiki.ubuntu.com/DebuggingTouchpadDetection.
  I have checked, if cursor moves with a mouse and it does. And there's
  no touchpad in /proc/bus/input/devices. So, I was recommended there to
  put it here as a bug.

[Kernel-packages] [Bug 1686189] Re: External monitor connecting problem on Intel graphics card

[mauro]

I tried to remove but if I do also this packeges will e removed

- lubuntu-core
- lubuntu-desktop

So I did apt-get install --reinstal xserver-xorg-video-intel but nothing
has changed.

If I plug in the VGA and open a window I can see that the system see the
monitor anch I can set via the 'monitor setting' what to show where but
the PC input of the TV doesn't highlight and can't connect/show remotely

Please advise if we need to open a new bug with this chipset rather than
continue here.

Would it be possible for you to see if changing lxd to use btrfs instead
of zfs on Bionic causes the bug?

[Kernel-packages] [Bug 1754621] [NEW] Builtin touchpad is not seen in 'DELL Latitude E5550' after the reboot during update.

[Anna Nikiforovskaya]

Public bug reported:

After an unexpected reboot, cursor disappeared. The only thing, which
helped -- typing

gsettings set org.gnome.settings-daemon.plugins.cursor active false

and rebooting again. However, cursor now doesn't move with a touchpad. I
have found this https://wiki.ubuntu.com/DebuggingTouchpadDetection. I
have checked, if cursor moves with a mouse and it does. And there's no
touchpad in /proc/bus/input/devices. So, I was recommended there to put
it here as a bug.

[Kernel-packages] [Bug 1754584] Re: system process hung on container stop/delete

[Joshua Powers]

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

This was the first time I have attempted this so I do not know about
previous kernels.

After installing 4.16-rc4 I could not re-attempt to reproduce because the zfs 
modules are not present:
modprobe: FATAL: Module zfs not found in directory 
/lib/modules/4.16.0-041600rc4-generic

I changed lxd to use btrfs instead of zfs and attempted to reproduce and
was not able to.

  I get the following

  # cat /proc/sys/net/ipv4/tcp_keepalive_time
  cat: /proc/sys/net/ipv4/tcp_keepalive_time: No such file or directory

  I'm informed from linuxcontainers.org, that this is a kernel bug.
  
https://discuss.linuxcontainers.org/t/why-is-there-no-tcp-keepalive-under-lxd/891

  I happen to be trying to run Kolab.org in a container, and some of their 
python code errors as this is parameter is not found. Clearly someone has found 
this in Kolab before as there's a patch
  
https://github.com/TBits/KolabScripts/blob/KolabWinterfell/kolab/patches/fixPykolabIMAPKeepAlive.patch
  But the problem is in other places too.

  It could be argued that Kolab should code round this issue.
  But on the other hand, with out it, and in general, other applications would 
not run in containers, which perhaps is a undesirable limitation.

  Thus it's why I'm reporting here.
  And there may be other parameters not appearing in the container too.

  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 4.4.114 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 4.4.114 stable release shall be
  applied:

[Kernel-packages] [Bug 1215411] Re: libcpupower.so is not installed from linux-tools

[Vlad Orlov]

So... the modified SONAME is apparently needed for the specific version
of cpupower tool to depend strictly on the corresponding version of
libcpupower.so.* from the same linux-tools-* package:

$ objdump -p /usr/lib/libcpupower.so.4.15.0-10  | grep SONAME
  SONAME   libcpupower.so.4.15.0-10

$ ldd /usr/lib/linux-tools-4.15.0-10/cpupower | grep libcpupower
libcpupower.so.4.15.0-10 => /usr/lib/libcpupower.so.4.15.0-10 
(0x7fb94ec4b000)

$ dpkg -S /usr/lib/linux-tools-4.15.0-10/cpupower
linux-tools-4.15.0-10: /usr/lib/linux-tools-4.15.0-10/cpupower

$ dpkg -S /usr/lib/libcpupower.so.4.15.0-10
linux-tools-4.15.0-10: /usr/lib/libcpupower.so.4.15.0-10

With such setup, it won't be possible to make mate-cpufreq-applet link
against a symlink (like libcpupower.so.1) instead of the versioned
library (like libcpupower.so.4.15.0-10).

I really don't know how to solve this without breaking that setup.
Anyone has any ideas?

  This isn't particularly suitable for projects that previously used

[Joseph Salisbury]

We should notify upstream since the bug still occurs with the latest
upstream kernel. Would it be possible for you to open an upstream bug
report[0]? That will allow the upstream Developers to examine the issue,
and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to
email the appropriate mailing list. If no response is received, then a
bug may be opened on bugzilla.kernel.org.

Once this bug is reported upstream, please add the tag: 'kernel-bug-
reported-upstream'.

Bug description:
  Distribution: Ubuntu 16.04 x64 (Flavour: KDE Neon User Edition 5.10)

  linux-image-4.4.0-81-generic appears to contain a regression, probably
  related to the CVE-2017-1000364 fix backport / patch.

  Using this kernel, the Oracle Java browser plugin always crashes
  during stack-related actions on initialization. This means, the plugin
  completely stopped working.

  
  It works perfectly fine in linux-image-4.4.0-79-generic (vurlerable to 
CVE-2017-1000364) as well as linux-image-4.11.6-041106-generic, which also 
contains a fix for CVE-2017-1000364.


  uname -a:

  > Linux Zweiblum 4.4.0-81-generic #104-Ubuntu SMP Wed Jun 14 08:17:06
  UTC 2017 x86_64 x86_64 x86_64 GNU/Linux


  I tested Oracle Java 1.8 u131 as well as 1.6 u64 in Firefox 51.0.1 as
  well as Iceweasel / Firefox/3.5.16 in a chroot.

  Using linux-image-4.4.0-81-generic it crashes in all combinations
  while with both other kernels it works.

  
  I was not able to obtain any detailed crash information from Firefox 51.0.1, 
but Iceweasel 3.5.16 crashed completely, allowing me to obtain a stack trace 
which shows the relation to stack operations performed by the plugin, even 
without proper debug symbols:

  
  > (gdb) bt full
  > #0  0x7fa06d805307 in _expand_stack_to(unsigned char*) () from 
/opt/java-8-oracle/jre/lib/amd64/server/libjvm.so
  > No symbol table info available.
  > #1  0x7fa06d8053ae in os::Linux::manually_expand_stack(JavaThread*, 
unsigned char*) ()
  >from /opt/java-8-oracle/jre/lib/amd64/server/libjvm.so
  > No symbol table info available.
  > #2  0x7fa06d80cf0b in JVM_handle_linux_signal () from

  > No symbol table info available.
  > #3  0x7fa06d802e13 in signalHandler(int, siginfo*, void*) () from 
/opt/java-8-oracle/jre/lib/amd64/server/libjvm.so
  > No symbol table info available.
  > #4  

  
  I first assumed a bug in the Java plugin, but it works fine in Linux 4.11.6.

  
  The crash will be triggered by any applet, for example the test applet at:

  * https://java.com/en/download/installed8.jsp

  
  I'm running the Ubuntu 16.04 based KDE Neon distribution which somehow 
apparently does not allow me to use apport to report this bug:

  > $ LANG= apport-cli linux-image-4.4.0-81-generic
  > 
  > *** Collecting problem information
  > 
  > The collected information can be sent to the developers to improve the

  > 
  > The problem cannot be reported:
  > 
  > This is not an official KDE package. Please remove any third party package 
and try again.

  If someone can tell me how to get apport working for this package, I
  can use it to collect additional information, but (unfortunately?) the
  problem should be fairly easy to reproduce...

  == SRU Justification ==
  Some SSD drives made by LiteOn can crash the kernel due to bad drivers. This 
is a
  regression introduced by commit e0edc8c54646.  This regression is fixed by 
mainline
  commit db5ff909798, which was added to mailine in v4.15-rc9.

  This commit has already been added to Bionic via upstream stable udpates.  
Xenial
  also needs this fix because it recieved the regression introducing commit 
e0edc8c54646
  via the 4.4.48 stable updates(See bug lp1663657).

  libata: apply MAX_SEC_1024 to all LITEON EP1 series devices

  == Regression Potential ==
  Low.  This commit was also cc'd to upstream stable to fix a regression, so it
  received extra upstream review.

  == 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.


  == Original Bug Description ==
  Some SSD drives made by LiteOn can crash the kernel due to bad drivers.  A 
fix for this issue has been submitted upstream: 
https://git.kernel.org/pub/scm/linux/kernel/git/tj/libata.git/commit/?h=for-4.15-fixes

  LITEON EP1 has the same timeout issues as CX1 series devices.

  Revert max_sectors to the value of 1024.

  devices")'

  Signed-off-by: Xinyu Lin 
  Signed-off-by: Tejun Heo 
  Cc: sta...@vger.kernel.org

  At a high level the root cause of this problem is that the device only
  supports commands with a transfer size up to 512KB.  This worked fine
  with older versions of Linux but newer versions are attempting
  commands with a transfer size of 1280KB which is problematic for this
  device (LITEON EP1-KB480)

[Kernel-packages] [Bug 1754581] Re: trusty bcache NULL pointer exception

[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.

[Kernel-packages] [Bug 1754584] Re: system process hung on container stop/delete

[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.

[Kernel-packages] [Bug 1754592] [NEW] Xenial update to 4.4.114 stable release

[Stefan Bader]

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 4.4.114 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 4.4.114 stable release shall be
applied:

** Affects: linux (Ubuntu)
 Importance: Undecided
 Status: New


** Tags: kernel-stable-tracking-bug

[Kernel-packages] [Bug 1748408] Re: Servers going OOM after updating kernel from 4.10 to 4.13

[Joseph Salisbury]

SRU request submitted:
https://lists.ubuntu.com/archives/kernel-team/2018-March/090701.html

** Description changed:

- We are seeing this on multiple servers after upgrading from previous
- 4.10 series HWE kernels to the new 4.13 HWE series. With the new kernel,
- free memory is continously decreasing at a high rate and the servers
- start swapping and finally OOMing services within days. With the 4.10
- kernel, decrease of free memory is slower and stabilizes after a while.
