[Kernel-packages] [Bug 1630063] Re: specific USB devices disconnect and don't reconnect

[Cody Smith]

Okay, spoke too soon, and found what might be the device causing all
this headache: my USB headset that works just fine with kernels before
this, but on 4.8 seems to cause issues with ohci-pci. The minute I plug
the headset in (or seconds afterwards), ohci-pci dies, so I'm thinking
it may be a driver issue.

  This only started happening when Yakkety went to the 4.8 branch, with 4.7 
branch this doesn't occur, hence the bug report since it's unlikely that a 
hardware failure will only stick to one OS and one branch of the kernel for 
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested 
that in the past couple of days)

[Kernel-packages] [Bug 1630063] Re: specific USB devices disconnect and don't reconnect

[Cody Smith]

Alright, results of that kernel aren't good, it doesn't even boot on my
system, it just hangs just after grub hands over. But there was a new
update for the 4.8 series, and for the meantime the usb bug doesn't seem
to have hit yet, we'll see if it does before the end of tomorrow.

[Cody Smith]

Sorry about the wait, had a drive mysteriously stop working (pinned the
issue to a faulty SATA cable, still took out a good portion of my
install), gonna try that here in a few minutes (meaning when I get the
packages installed). I'll report back with the results.

  This only started happening when Yakkety went to the 4.8 branch, with 4.7 
branch this doesn't occur, hence the bug report since it's unlikely that a 
hardware failure will only stick to one OS and one branch of the kernel for 
that OS. (these USB ports don't randomly die on Windows or BSD, I've tested 
that in the past couple of days)

  I can't use my mouse to click anything inside the Ubuntu (Unity) 16.10

  Or open the VM Settings. Switch to the System tab and make sure "Enable I/O

[Kernel-packages] [Bug 1441852] Re: [HP Spectre x360 - 13-4010ca] Audio broken, broadwell-U audio controller

[madbiologist]

Can everyone please test the 4.9-rc1 kernel when it is available at 
http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D
It contains the following commit:

ALSA: hda - Add the top speaker pin config for HP Spectre x360

HP Spectre x360 with CX20724 codec has two speaker outputs while the
BIOS sets up only the bottom one (NID 0x17) and disables the top one
(NID 0x1d).

This patch adds a fixup simply defining the proper pincfg for NID 0x1d
so that the top speaker works as is.

[Kernel-packages] [Bug 1630069] Re: Regression tests can not detect binfmt_elf mmpa semantic change

[Tyler Hicks]

The Yakkety apparmor package does not need this change since the Yakkety
kernel will always have kernel commit
9f834ec18defc369d73ccf9e87a2790bfa05bf46 present.

** Description changed:

  With the recent upstream commit 9f834ec18defc369d73ccf9e87a2790bfa05bf46
  the cred used for the mmap changed resulting in test failures. The tests
  have been patched for this change but it results in the test breaking
  for everyone using upstream releases against pre 4.8 kernels.

[Kernel-packages] [Bug 1629661] Re: Hissing sound in headphones

[LGB [Gábor Lénárt]]

$ uname -a
Linux oxygene 4.8.0-040800-generic #201610022031 SMP Mon Oct 3 00:32:57 UTC 
2016 x86_64 x86_64 x86_64 GNU/Linux

The really same. Moreover, this hissing sound can be heard with BIOS/etc
too, without any OS, it's even more louder then.

The issue started with this machine, I didn't have it with previous
ubuntu versions ...

Title:
  Hissing sound in headphones

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 16.04 on 64 bit produces hissing sound (just by my - far from
  being 'musical' - ear, it sounds like a sinus wave with frequency
  about 1KHz or so) on headphones. Interestingly, after boot this does
  not happen and usually can be hear only after the first application
  which makes any sound (but not always, sometimes it starts later). But
  if any time it starts, it remains, whatever I do, exiting the
  application (which makes the sound) even by killing pulseaudio
  process, etc. I've read a lot on this issue but usually - it seems -
  always notebook problems mentioned, however it's a desktop machine
  (Asrock FM2A88M extreme4+ motherboard, AMD A6-6400K CPU, integrated
  audio). It seems it uses snd_hda_intel kernel module though. I've
  tried advices mentioned by various resources throughout the net,
  disabling powersave problems, using hdajackretask from alsa-tools-gui,
  etc, but they didn't help.

Bug description:
  [Impact]

   * zfs services fail on firstboot if zfs-utils is integrated into the
  deployment image.

   * Output from systemd -
  sudo systemctl --failed
  UNIT LOAD ACTIVE SUB DESCRIPTION
  ● zfs-import-scan.service loaded failed failed Import ZFS pools by device 
scanning
  ● zfs-mount.service loaded failed failed Mount ZFS filesystems

   * This is particularly frustrating for users who use automated
  monitoring as it means virtual machines must always be restarted
  before showing as clean.

   * This failure is due to zfs services starting up before /etc/mtab
  has a chance to be symlinked to /proc/mounts.

  [Test Case]

   1. Grab a stock xenial image, and unpack it and add zfs-utils to it.  Repack 
it.
   2. Boot machine
   3. Check systemctl --failed.

  [Regression Potential]

   * none expected, patch has been intensively tested by the upsteam zfs
  test script suite.

   * This is a upstream commit merge in 0.7.0.

   * A ubuntu package has been tested (including the upstream commit) by
  a user of the community facing this bug, and confirmed it addresses
  the problem (see comment #7).

  [Other Info]

  * The "reading" is redirected to /proc/self/mounts. 
  The writing to /etc/mtab. Some distros still need that. The current hope is 
to replace the writing (and maybe reading) with libmount, in a second phase.

Re: [Kernel-packages] [Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Anmar Oueja]

Guys, there is an entry on the Chromium site talking about xorg modesetting
vs intel xorg driver. By installing modesetting module and getting rid of
the intel driver, the flicker was gone completely on Ubuntu 16.04.

[Kernel-packages] [Bug 1085766] Re: /var/log/upstart/ureadahead.log contains garbage

[xb5i7o]

I can confirm i am having the same issue on Xenial, my syslog gets
flooded with millions of ureadahead messages, i restarted and i havent
seen it happen as yet again. This usually happens when you start up the
PC.

What is ureadahead??

  It appears that the latest i40e driver in Trusty is 0.3.36-k.  We've
  been experiencing some kernel panics with this driver and have found
  that it looks like bringing the driver up to the latest 1.2.48 has
  alleviated some of the kernel panics on boot.

  Is this something we could look at getting upgraded to a more modern
  revision of the driver?

  [Impact]

   * zfs services fail on firstboot if zfs-utils is integrated into the
  deployment image.

   * Output from systemd -
  sudo systemctl --failed
  UNIT LOAD ACTIVE SUB DESCRIPTION
  ● zfs-import-scan.service loaded failed failed Import ZFS pools by device 
scanning
  ● zfs-mount.service loaded failed failed Mount ZFS filesystems

   * This is particularly frustrating for users who use automated
  monitoring as it means virtual machines must always be restarted
  before showing as clean.

   * This failure is due to zfs services starting up before /etc/mtab
  has a chance to be symlinked to /proc/mounts.

  [Test Case]

   1. Grab a stock xenial image, and unpack it and add zfs-utils to it.  Repack 
it.
   2. Boot machine
   3. Check systemctl --failed.

  [Regression Potential]

   * none expected, patch has been intensively tested by the upsteam zfs
  test script suite.

   * This is a upstream commit merge in 0.7.0.

   * A ubuntu package has been tested (including the upstream commit) by
  a user of the community facing this bug, and confirmed it addresses
  the problem (see comment #7).

  [Other Info]

  * The "reading" is redirected to /proc/self/mounts. 
  The writing to /etc/mtab. Some distros still need that. The current hope is 
to replace the writing (and maybe reading) with libmount, in a second phase.

  
   * Upstream commit :

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

If that kernel is also bad, then the next one is already ready and can
be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1627108/3d89e5478bf550a50c99e93adf659369798263b0/

However, if it is good, I'll have to build the next kernel with a good
result.

Title:
  X1Carbon comes to a crawl during high CPU usage tasks

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

Bug description:
  My X1Carbon becomes quite laggy, the cursor hangs for a few seconds
  and then resumes while my system is compiling some code, or lets says
  PyCharm is indexing things or Android Studio is compiling some code. I
  was using 4.4 on Xenial a few days ago and everything was working just
  fine. Installed Yakkety and this issue happens.

  I will downgrade the kernel and see if that mitigates the issue.

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

I pointed you to the wrong kernel in comment #26.  The URL should have
been:

http://kernel.ubuntu.com/~jsalisbury/lp1627108/55e16d30bd99510900caec913c90f53bc2b35cba/

Can you test that kernel?

Title:
  X1Carbon comes to a crawl during high CPU usage tasks

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

Bug description:
  My X1Carbon becomes quite laggy, the cursor hangs for a few seconds
  and then resumes while my system is compiling some code, or lets says
  PyCharm is indexing things or Android Studio is compiling some code. I
  was using 4.4 on Xenial a few days ago and everything was working just
  fine. Installed Yakkety and this issue happens.

  I will downgrade the kernel and see if that mitigates the issue.

[Kernel-packages] [Bug 1590590] Re: Touchpad not recognized on Dell Latitude E7470 Ultrabook

[dashesy]

Same problem as above on Dell 7510, thinks it is PS/2. Normally that
would not be a problem, but this specific touchpad by default uses
"natural scrolling" which is very annoying.

  The touchpad on my Dell Ultrabook (Latitude E7470) functions mostly. 

  The settings for the touchpad are not available at all in the Mouse

  Two-finger scrolling works as expected except it's using "Natural
  Scrolling" by default and there is no way to change it.

[Kernel-packages] [Bug 1435040] Re: Ubuntu Phone does not connect to car-bluetooth

[Vincas Dargis]

With OTA13 I cannot even pair with Parrot CK3100. Tried to forget
pairing on both sides but it did not help. My BQ E5 shows "unknown"
device instead of "Parrot..".

pre-OTA13 I could pair, sync contacts, but there was no sound.

Status in linux package in Ubuntu:

Bug description:
  During some tests I've encountered an issue with kdump through NMI SMP
  and single core. After kdump configuration, when I trigger the crash
  through an NMI call from the host, the VM will panic, however it will
  not write the vmcore dump files and neither reboot.

  REPRO STEPS:

  1. configure kdump
   - crashkernel=512M-:384M  /boot/grub/grub.cfg
   - USE_KDUMP=1 /etc/default/kdump-tools

  2. after configuration reboot the VM

  3. check kdump status
   - cat /sys/kernel/kexec_*
   - service kdump-tools status

  4. configure NMI
   - sysctl -w kernel.unknown_nmi_panic=1

  5. trigger a crash from host
   - Debug-VM -Name $vmName -InjectNonMaskableInterrupt -ComputerName $hvServer 
-Force

[Kernel-packages] [Bug 1618678] Re: Disk Device Driver Reported Error: DID_ERROR ... DRIVER SENSE

[Øyvind Stegard]

Christopher, I think there is an upstream bug report for this problem:
https://bugzilla.kernel.org/show_bug.cgi?id=153241

(I thought my hard drive was dying when these messages suddenly appeared
on a server running Ubuntu 14.04 with 4.4.0-38-kernel.)

[Kernel-packages] [Bug 1629613] Re: [Dell XPS 13] SynPS/2 Synaptics TouchPad not recognized after upgrade from 14.04 to 16.04

[Matthieu Dubuget]

I'm confirming this bug: I upgraded my XPS 13 9333 from 14.04 to 16.04 last 
week.
I had to go back to 14.04 by restoring the hard drive image because I was not 
able to have the touchpad working. I also tested the generic kernel without 
more success.

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
55e16d30bd99510900caec913c90f53bc2b35cba

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627108/766fd5f6cdaf1d558afba19850493b2603c9625d

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

  My X1Carbon becomes quite laggy, the cursor hangs for a few seconds

  PyCharm is indexing things or Android Studio is compiling some code. I
  was using 4.4 on Xenial a few days ago and everything was working just
  fine. Installed Yakkety and this issue happens.

  I will downgrade the kernel and see if that mitigates the issue.

[Kernel-packages] [Bug 1629962] Re: Bluetooth: "device descriptor read/64, error -110" on cold boot

[Valdas]

Removed virtualbox-dkms, video driver changed from NVIDIA to Nouveau, installed 
kernel v 4.8.0-040800, three times performed cold boot (dmesg' outputs 
attached): boot times was much shorter, BUT dmesg still prints that "error 
-110".
 Removed kernel 4.8 (not installed virtualbox-dkms, video driver still 
Nouveau): returned to previous state with long boot and errors in dmesg output.

** Attachment added: "Three dmesg outputs using kernel v4.8."

Bug description:
   Every time when I turn on my laptop using Power button I always get a
  long pause at bootup. I experience this behavior about half of year or
  so I think (with 14 LTS I had no pause at bootups).

   I analyzed dmesg output (full printout is attached) and found that cause for 
this pause is integrated bluetooth (notice pause ends at 23 second):

   In fully booted system bluetooth is working without problems.

   Later restarts don't produce mentioned pause and dmesg doesn't show
  mentioned errors.

[Kernel-packages] [Bug 1609242] Re: Kernels 4.3-4.8 result in blackscreen - Intel Ivybridge

[aproposnix]

Same issue as before. As with all of the 4.1 kernels, the screen freezes
before going into Plymouth. Only the cursor is visible and I have to
manually restart the computer.

  Kernels 4.3-4.8 result in blackscreen - Intel Ivybridge

Status in linux package in Ubuntu:

Status in linux source package in Xenial:
  In Progress

Bug description:
  When I install Ubuntu 16.04 on my computer the screen goes blank at
  login. I can blindly login and it boots but I cannot use the display
  (external monitor through HDMI).

  I've looked online for an answer to this issue but could not find a
  solution.  However, many people report this issue in forums with the
  4.4x kernel.

  On my main computer, I upgraded from 14.04 to 16.04.1. On this
  computer I was able to switch back to the 3.13 kernel which *does
  work*.

  On the same computer, if I use a 16.04 live CD, it does the same
  thing.  The screen goes blank.

  UEFI may be part of the issue as well.  I have it disabled in bios
  (set to legacy mode) but when I first boot, it seems to go into UEFI
  mode first and then, after rebooting with  it shows
  me the list of kernels. I can select the kernel from there but if I
  use a 4.4x kernel, it blanks out at encryption passphrase screen.

  There are also people with similar issues on AskUbuntu.

  Here's some basic HW info.  If you require more, please ask.

  Bluetooth: "device descriptor read/64, error -110" on cold boot

Status in linux package in Ubuntu:

Bug description:
   Every time when I turn on my laptop using Power button I always get a
  long pause at bootup. I experience this behavior about half of year or
  so I think (with 14 LTS I had no pause at bootups).

   I analyzed dmesg output (full printout is attached) and found that cause for 
this pause is integrated bluetooth (notice pause ends at 23 second):
  $ dmesg|grep "usb 1-1.1"

   In fully booted system bluetooth is working without problems.

   Later restarts don't produce mentioned pause and dmesg doesn't show
  mentioned errors.

continued to experience screen flash while using google-chrome-beta

  *** Temporary workaround ***
  Install Kernel from the following location:

  - $ apt update
  - $ apt install linux-image-extra-4.6.0-6-generic

  ```
  There was a typo in instructions (/etc/preferences.d should have been 
/etc/apt/preferences.d).
  As result you might have upgraded Linux META packages and therefor you won't 
receive proper upgrades of Xenial native Linux packages (hoping they will ever 
contain the fix).
  I suggest you move 
/etc/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety to 
/etc/apt/preferences.d/ and downgrade related packages:
  $ apt update
  $ apt install linux-headers-generic/xenial-updates

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
766fd5f6cdaf1d558afba19850493b2603c9625d

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627108/766fd5f6cdaf1d558afba19850493b2603c9625d

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

[Kernel-packages] [Bug 1584597] Re: Hyper-V Memory Ballooning re-broken in 16.04

[Alex Ng]

Evan, from your screenshots, I can see that the memory demand values and
the /proc/meminfo values do match closely to each other.

On the 16.04.01 VM, /proc/meminfo shows Committed_AS value is ~1800MB.
The balloon driver then adds a buffer of ~300MB (this buffer is
calculated according to how much total memory is assigned to the VM). So
~1800MB + ~300MB = 2100MB matches closely with the 2088 MB memory demand
that you're seeing from the host.

A similar calculation on the 15.10 VM also shows that the meminfo values
match closely with the reported memory demand. (~2900MB committed +
~500MB buffer = 3400MB compared to 3600MB)

The main culprit in both cases appears to be the large amount of
committed memory. Would be worth investigating what the cause of this
memory usage is.

  Regression: #1294283 fixed memory ballooning in Hyper-V in 14.04, but
  the bug has returned in 16.04.

  
  Steps to reproduce:

  1. Create Gen2 Hyper-V VM
  2. Install Ubuntu 16.04
  3. modprobe hv_balloon
  Memory usage according to Hyper-V Manager will not change

  
  This has been reproduced on 2 fresh Ubuntu Server 16.04 instances.

  I installed linux-generic-xenial on a 14.04 instance, rebooted,
  modprobe'd hv_balloon and memory usage in Hyper-V Manager reduced to
  the correct level.

  Host: Windows NanoServer 2016

[Kernel-packages] [Bug 1628662] Re: USB soundcard fails on resume

[lol24h]

O right! I tried this one
Linux slice 4.8.0-040800rc8-generic #201609252231 SMP Mon Sep 26 02:33:23 UTC 
2016 x86_64 x86_64 x86_64 GNU/Linux

And ... once, the first time it worked correctly.But the next one it
failed and on all the other trials.

However I noticed, that happens only on the dock port! Then I thought,
ok try the ones on the body.

The USB 3.0 port works EVERYTIME after the suspend. The issue happens
only on USB 2.0 ports (both dock and the only one on the body).

  *** Temporary workaround ***
  Install Kernel from the following location:

  OR
  Perform the following:
  - $ apt-add-repository "deb

  - $ apt install linux-image-extra-4.6.0-6-generic

  ```
  There was a typo in instructions (/etc/preferences.d should have been 
/etc/apt/preferences.d).
  As result you might have upgraded Linux META packages and therefor you won't 
receive proper upgrades of Xenial native Linux packages (hoping they will ever 
contain the fix).
  I suggest you move 
/etc/preferences.d/canonical-kernel-team-ubuntu-ppa-yakkety to 
/etc/apt/preferences.d/ and downgrade related packages:
  $ apt update
  $ apt install linux-headers-generic/xenial-updates

[Kernel-packages] [Bug 1584597] Re: Hyper-V Memory Ballooning re-broken in 16.04

[Alex Ng]

Bernhard(galmok), the memory corruption you're seeing is likely a known
issue that happens when Linux guests are running on Windows Server 2012.
This was fixed recently in the upstream Linux kernels, so hopefully a
future update will have these patches.

  Hyper-V Memory Ballooning re-broken in 16.04

Bug description:
  Regression: #1294283 fixed memory ballooning in Hyper-V in 14.04, but
  the bug has returned in 16.04.

  
  Steps to reproduce:

  1. Create Gen2 Hyper-V VM
  2. Install Ubuntu 16.04
  3. modprobe hv_balloon
  Memory usage according to Hyper-V Manager will not change

  
  This has been reproduced on 2 fresh Ubuntu Server 16.04 instances.

  I installed linux-generic-xenial on a 14.04 instance, rebooted,
  modprobe'd hv_balloon and memory usage in Hyper-V Manager reduced to
  the correct level.

  Environment:
  Host: Windows NanoServer 2016

  Ubuntu Server 16.04 version_signature: `Ubuntu 4.4.0-21.37-generic 4.4.6`
  Ubuntu Server 14.04 version_signature: `Ubuntu 4.4.0-22.40~14.04.1-generic

Re: [Kernel-packages] [Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Anmar Oueja]

Yikes. In your case it isn't the browser for sure. I read somewhere that
the adaptive brightness control might be a culprit but don't count on that
being true unless confirmed.

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
3ebfd81f7fb3e81a754e37283b7f38c62244641a

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627108/3ebfd81f7fb3e81a754e37283b7f38c62244641a

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

Bug description:
  My X1Carbon becomes quite laggy, the cursor hangs for a few seconds
  and then resumes while my system is compiling some code, or lets says
  PyCharm is indexing things or Android Studio is compiling some code. I
  was using 4.4 on Xenial a few days ago and everything was working just
  fine. Installed Yakkety and this issue happens.

  I will downgrade the kernel and see if that mitigates the issue.

[Kernel-packages] [Bug 1554613] Re: Screen flickers on XPS 13 9350/9550 (Intel Skylake/Broadwell GPU)

[Thiago Martins]

Anmar,

I am 100% sure that it is not the browser, please guys, watch this:

https://www.youtube.com/watch?v=BC287yYPfTA

This BUG is not fixed. Or maybe, what I'm seeing here is a different
bug.

On Ubuntu 16.10, things looks a little bit better but, Chrome still
flickers.

Ubuntu 14.04 is fine. While 16.04 and 16.10 are just terrible.

[Kernel-packages] [Bug 1630459] Re: Ralink rt5390 unstable connection on ubuntu 16.04.1

[Julio Palazón]

The notebook is a HP Pavilion g6 2016ss. The router is provided by my
ISP with proprietary firmware, so it isn't a standard commercial model.
I think it's irrelevant, since Fedora 24 with kernel 4.7 and Centos 7.2
with 3.10 kernel are working fine.

Testing the Ubuntu setup, I've found that Wicd has the dropping
connection issue, but it reconnects immediatly. NetworkManager needs a
reboot before it is able to reconnect.

I'm testing the kernel 4.8 with default NetworkManager setup, as you
have asked for.

Thanks.

(Sorry for my bad english)

[Kernel-packages] [Bug 1470250] Re: [Hyper-V] Ubuntu 14.04.2 LTS Generation 2 SCSI Errors on VSS Based Backups

[Joseph Salisbury]

I'm still working on getting a Trusty test kernel build with both
patches.  Alexs' patch is requiring some prereq commits to work with
Trusty.  I should have a test kernel ready shortly.

  This relates to the VSS "Windows Server Backup" process that kicks off at 
midnight on the host and finishes an hour and half later.   
  Yes, we do have hv_vss_daemon and hv_kvp_daemon running for the correct 
kernel version we have.   We're currently running kernel version 
3.13.0-49-generic #83 on one system and 3.16.0-34-generic #37 on the other. -- 
We see the same errors on both.
  As a result, we've been hesitant to drop any more ubuntu guests on our 2012R2 
hyper-v system because of this.   We can stop the backup process and all is 
good, but we need nightly backups to image all of our VM's.   All the windows 
guests have no issues of course.   We also have some CentOS based guests 
running without issues from what we've seen.

Bug description:
  When I install Ubuntu 16.04 on my computer the screen goes blank at
  login. I can blindly login and it boots but I cannot use the display
  (external monitor through HDMI).

  I've looked online for an answer to this issue but could not find a
  solution.  However, many people report this issue in forums with the
  4.4x kernel.

  On my main computer, I upgraded from 14.04 to 16.04.1. On this
  computer I was able to switch back to the 3.13 kernel which *does
  work*.

  On the same computer, if I use a 16.04 live CD, it does the same
  thing.  The screen goes blank.

  UEFI may be part of the issue as well.  I have it disabled in bios
  (set to legacy mode) but when I first boot, it seems to go into UEFI
  mode first and then, after rebooting with  it shows
  me the list of kernels. I can select the kernel from there but if I
  use a 4.4x kernel, it blanks out at encryption passphrase screen.

  There are also people with similar issues on AskUbuntu.

  Here's some basic HW info.  If you require more, please ask.

[Kernel-packages] [Bug 1627108] Re: X1Carbon comes to a crawl during high CPU usage tasks

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
c86ad14d305d2429c3da19462440bac50c183def

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1627108

Can you test that kernel and report back if it has the bug or not? I
will build the next test kernel based on your test results.

Thanks in advance

Bug description:
  My X1Carbon becomes quite laggy, the cursor hangs for a few seconds
  and then resumes while my system is compiling some code, or lets says
  PyCharm is indexing things or Android Studio is compiling some code. I
  was using 4.4 on Xenial a few days ago and everything was working just
  fine. Installed Yakkety and this issue happens.

  I will downgrade the kernel and see if that mitigates the issue.

Bug description:
  Builders were changed from wily to xenial (4.4) kernel for arm64, and
  likely due to this the following kind of errors started happening:

  https://launchpadlibrarian.net/288487533/buildlog_ubuntu-yakkety-arm64
  .ubuntu-push-qml_0.1+15.10.20150826.1-0ubuntu2_BUILDING.txt.gz

  They happen when executing QML code.

  I've ruled out that reverting to previous qtbase and qtdeclarative
  versions don't affect this, so it's not coming from a Qt change. I've
  also verified there's no problem eg on our Bq tablet running the same
  tests on xenial+overlay. There are currently no found changes at least
  in Qt upstream to backport arm64 related fixes.

  Cause is unknown. But the same problem is there on vivid, xenial and yakkety 
builds:
  
https://launchpadlibrarian.net/288516465/buildlog_ubuntu-yakkety-arm64.online-accounts-api_0.1+16.10.20161006.1-0ubuntu1_BUILDING.txt.gz

  This means it does not matter if it's Qt 5.4 or 5.6, GCC 4.9, 5 or 6,
  or glibc 2.21, 2.23 or 2.24.

[Tim Gardner]

Without hardware it is difficult for us to reproduce these kinds of
issues if they are unique to ppc64el. I suggest that you are going to
need IBM developer assistance. Also, the attached lock torture script is
incomplete in that it requires 'test.sh' which does not exist.

Correction to the code url:

(5.6.1 branch doesn't exist over there, but code seems unchanged)

Great news! until that happens, is there any harm in leaving 4.8 or
4.4.23 running on the current compute nodes?

  [arm64] compute nodes unstable after upgrading from 4.2 to 4.4 kernel

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

Bug description:
  Hi,

  In order to investigate bug LP#1531768, we upgraded some arm64 compute
  nodes (swirlices) to a 4.4 kernel. I think it made the VMs work
  better, but the hosts became extremely unstable.

  After some time, getting a shell on them would be impossible.
  Connecting on the VSP, you'd get a prompt, and once you typed your
  username and password, you'd see the motd but the shell would never
  spawn.

  Because of these instability issues, all the arm64 compute nodes are
  now back on 4.2. However, we managed to capture "perf record" data
  when a host was failing. I'll attach it to the bug. Perhaps it will
  give you hints as to what we can do to help you troubleshoot this bug
  further.

  Once we have your instructions, we'll happily reboot one (or a few)
  nodes to 4.4 to continue troubleshooting.

  Thanks !

Title:
  sg devices are not being created for SCSI storage controller devices
  starting from v4.4.0-30

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Most storage array expose a store controller device to logical unit 0.
  Following LP #1567602, when this happens and the alua driver is loaded, 
Ubuntu doesn't create the sg device for it, and linux fails to discover the 
disks that are attached to higher logical unit numbers.

  With kernel version 4.4.0-31, we tried a number of things:
  - With a disk mapped to LUN0, everything is working.
  - Without a disk mapped to LUN0, nothing works - linux doesn't see disks 
mapped to higher LUNs, calling rescan_scsi_bus throws a stack trace to syslog: 
https://gist.github.com/grzn/20c05ce3fc96062ec9572fd5b8093b55
  - When turning on SCSI logging to the maximum 
(https://access.redhat.com/articles/337903 - 0xfff), we see that after ALUA 
driver rejected the SCSI controller nothing happens (look for 18:0:0:0 which is 
a controller here 
(https://gist.github.com/grzn/f8b65dd07b2df5f3f72ca8121d8c93ad) vs 19:0:00 
which is a disk here 
(https://gist.github.com/grzn/48da86b7f7390dab2983927862cda949).
  - When removing the scsi_dh_alua driver and then reloading the lpfc driver, 
everything is working as expected when no disk is mapped to LUN0.

[Kernel-packages] [Bug 1626983] Re: [Ubuntu16.10]KV4.8: kernel livepatch config options are not set

[Tim Gardner]

debian.master/config/config.common.ubuntu:CONFIG_HAVE_LIVEPATCH=y
debian.master/config/config.common.ubuntu:CONFIG_LIVEPATCH=y

Live patching is a common setting. If it doesn't exist in the installed
config, then it is because live patching is not supported on that
architecture.

[Kernel-packages] [Bug 1630906] Re: QML segfault on arm64 due to builder kernel change

[Timo Jyrinki]

I got a temporary access (now revoked) to an arm64 box where I could
reproduce the segfault by running qmlplugindump.

Here's the backtrace:

Where the code in question is

I hope that helps somehow.

  Builders were changed from wily to xenial (4.4) kernel for arm64, and

  They happen when executing QML code.

  I've ruled out that reverting to previous qtbase and qtdeclarative
  versions don't affect this, so it's not coming from a Qt change. I've
  also verified there's no problem eg on our Bq tablet running the same
  tests on xenial+overlay. There are currently no found changes at least
  in Qt upstream to backport arm64 related fixes.

  Cause is unknown. But the same problem is there on vivid, xenial and yakkety 
builds:

  Andrew Donnellan - Sept. 10, 2015, 6:28 a.m.
  1)  Export pcibios_free_controller(), so it can be used by the cxl module to
  free virtual PHBs.

   arch/powerpc/kernel/pci-common.c | 1 +
   1 file changed, 1 insertion(+)

  2) When adding a vPHB in cxl_pci_vphb_add(), we allocate a pci_controller
  struct using pcibios_alloc_controller(). However, we don't free it in
  cxl_pci_vphb_remove(), causing a leak.

  Call pcibios_free_controller() in cxl_pci_vphb_remove() to free the vPHB
  data structure correctly.

[Kernel-packages] [Bug 1602577] Re: [arm64] compute nodes unstable after upgrading from 4.2 to 4.4 kernel

[Junien Fridrick]

OK cool. I think we can wait. Do you have an ETA for the fix to come
down ? And will trusty also get the fix ?

  [arm64] compute nodes unstable after upgrading from 4.2 to 4.4 kernel

Status in linux package in Ubuntu:

Bug description:
  Hi,

  In order to investigate bug LP#1531768, we upgraded some arm64 compute
  nodes (swirlices) to a 4.4 kernel. I think it made the VMs work
  better, but the hosts became extremely unstable.

  After some time, getting a shell on them would be impossible.
  Connecting on the VSP, you'd get a prompt, and once you typed your
  username and password, you'd see the motd but the shell would never
  spawn.

  Because of these instability issues, all the arm64 compute nodes are
  now back on 4.2. However, we managed to capture "perf record" data
  when a host was failing. I'll attach it to the bug. Perhaps it will
  give you hints as to what we can do to help you troubleshoot this bug
  further.

  Once we have your instructions, we'll happily reboot one (or a few)
  nodes to 4.4 to continue troubleshooting.

  Thanks !
