[Kernel-packages] [Bug 1551880] [NEW] [Dell XPS 13 9343] Audio broken with I2S mode in Ubuntu 16.04

[der_eismann]

Public bug reported:

I wanted to try Linux again on this machine and the tons of
troubleshooting since release got a bit better, but the sound is still a
bit strange.

So after changing distributions I installed Xubuntu 16.04 Beta 1 today with 
kernel 4.4.0-8 and sound isn't working because the 3,5 mm device is completely 
missing. PulseAudio is only showing the HDMI output. 
I got the sound working by downloading kernel 4.3.6 from the Ubuntu kernel 
archives, although then it looks like it is running in HDA mode instead of I2S 
(which I don't like because Dual Boot).

Let me know if there is anything else I can do to track down the
problem.

[Kernel-packages] [Bug 1551854] Re: LXD bootstrap issues on xenial

[Serge Hallyn]

Also cannot reproduce in a clean VM, so I have to assume juju is
tweaking something.

Can you show output of 'lxc config show ' where 
is the container which fails?

Bug description:
  I'm using lxd with zfs block storage on xenial, and having issues with
  trusty containers. I've witnessed this problem when trying to
  bootstrap as well as after rebooting the host and a container failed
  to start.

  In the latter case, the container that failed to start was the juju
  controller:

  I manually started it, but found that no upstart services were
  started. Remembering this thread,
  https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
  checked /var/log/mountall.log in the machine-0 container, and sure
  enough:

  root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat 
/var/log/upstart/mountall.log
  mount: permission denied
  mountall: mount /sys/kernel/debug [187] terminated with status 32
  mountall: Filesystem could not be mounted: /sys/kernel/debug

  The problem persists if I stop and start the container. If I remount
  /sys/kernel/debug on the host, then stop and start the container,
  upstart succeeds and the juju controller starts up.

[Kernel-packages] [Bug 1547619] Re: Intermittent screen blinking with 4k external mini display port with 4.4 kernels

[Joseph Salisbury]

I started a kernel bisect between v4.3 final and v4.4-rc1. The kernel
bisect will require testing of about 13 test kernels.

I built the first test kernel, up to the following commit:
118c216e16c5ccb028cd03a0dcd56d17a07ff8d7

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1547619

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

  Intermittent screen blinking with 4k external mini display port with

Bug description:
  When using an external 4K monitor plugged into the mini display port on my 
Dell XPS 13 9343 using both the laptop screen and the external monitor 
(external monitor is left and laptop screen right), when using all of the 
following kernels:
  4.4.0-2.16-generic
  4.4.0-4.19-generic
  4.4.0-6.21-generic
  4.4.0-7.22-generic

  the external monitor will sometimes blink off for about a second or
  two, then back on. What is weird is this seems to only happen when
  typing into a gnome-terminal as opposed to firefox or evolution.
  Simply changing to a gnome-terminal and typing into it doesn't cause
  the blinking, but it might happen immediately or it might take several
  minutes.

  4.3.0-7.18-generic worked fine and I can go hours and hours in a
  gnome-terminal with no issues.

Title:
  memory leak in hv_storvsc (3.13.0-63-generic)

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

Bug description:
  Slab and SUnreclaim values in /proc/meminfo keep increasing. On one
  servers it reached 85% of physical memory after 14 days - but on most
  other servers it increases more slowly. I checked /proc/slabinfo and
  almost all allocations were in kmalloc-512. So I enabled
  "slub_debug=U,kmalloc-512" on one server, and after only 24h of uptime
  11% of the memory was used by kmalloc-512 and unreclaimable. With
  debugging enabled I could see the following in
  /sys/kernel/slab/kmalloc-512/alloc_calls:

  521294 storvsc_queuecommand+0x359/0x790 [hv_storvsc]
  age=161922/955116/20882927 pid=1-41545

  All other counters were below 2000. In
  /sys/kernel/slab/kmalloc-512/free_calls I see the following:

  516823  age=4315783846 pid=0

  The hv_storvsc module is for Hyper-V. We are (unfortunately) running
  Hyper-V 6.3.9600.16384 with Microsoft System Center 2012 R2 Update
  rollup 3 for all the servers with this issue.

  Kernels are stock linux-image-3.13.0-63-generic, 3.13.0-63.103,
  x86_64, from Ubuntu 14.04 LTS . /proc/version_signature contains:

Ubuntu 3.13.0-63.103-generic 3.13.11-ckt25

  No output from lspci -vnvn. The problem described above happens on
  both single and multicore virtual machines. CPU in hypervisors are
  E5-2630 v2 @ 2.60GHz. Let me know if you need more info or if I can do
  more debugging.

  Regards,

  Oskar Liljeblad

[Kernel-packages] [Bug 1500242] Re: Bluetooth devices (Jabra BT250, Audi A3 car kit) can not be connected with BQ Aquaris 4.5

[Uranicus]

@Simon

Thanks for picking this up again.

Topic 1. Audio A3: I will test this this evening or tomorrow and will
give you a feedback. I am very sure that the pin I have entered was
correct but I will check this again.

Topic 3. Logitec Bluetooth Mouse
For both channels (OTA9.1 & rc-proposed (current: 270)) I can now connect the 
mouse. Output during pairing is:

[NEW] Device 00:80:00:00:15:76 Bluetooth Mouse
[CHG] Controller 4C:74:03:64:75:ED Discoverable: no

[CHG] Device 00:80:00:00:15:76 Paired: yes
[CHG] Device 00:80:00:00:15:76 Trusted: yes

I was mistaken myself and therefore also my writing in the past: this in
NOT a Logitech mouse. It is LogiLink (looks like Logitech, ...) and the
packaging simply states: ID0078.


Do you need any more information for topic 2. Jabra headset?

Thanks for the work,

Matthias

Bug description:
  STEPS:
  Requirements: Aquaris E4.5, Jabra BT250 blue tooth handset device (rather old 
one supports blue tooth 1.1 and therefore I thought should be no issue) or Audi 
car kit (A3 2012 model)

  1. Put Jabra BT250 into receiving mode
  2. Phone searches automatically every 15 - 30 seconds for a new blue tooth 
device
  3. Phone finds Jabra BT250 and asks for pairing code
  4. Enter code into phone
  5. Jabra BT250 automatically exits the pairing mode (which is a sign that 
pairing should have worked)
  6. Phone looses connection to Jabra BT250
  7. Manual reconnection via phone works (shows Jabra BT250 as being connected) 
but ignores the device

  Same behaviour with Audi car kit (Audi A3, 2012 model)

  EXPECTED:
  I expect that the blue tooth kits work similar to my Seat Alhambra (also 2012 
model) where the blue tooth pairing etc. works great (except some bugs which 
are already filed).

  ACTUAL:
  No connection to the blue tooth device

  VERSIONS:
  OS-Build-Number: 25
  Ubuntu-Image: 20150825.1

  POSSIBLE ROOT CAUSE:
  Is this issue also solved as soon as bluez5 is implemented? When will this be?

  [Jawbone ERA] HFP features not working with Bluez5

Status in Canonical System Image:
  New
Status in bluez package in Ubuntu:
  In Progress

Bug description:
  While debugging some re-factoring work on the ofono upower plugin, I
  noticed that I wasn't able to answer or terminate calls using my
  Jawbone ERA headset.  I bought this headset last year, and although
  it's an older model, it's spec sheet states that it supports HSP 1.1,
  and HFP 1.5.

  I can pair the device with my krillin, and it properly auto connects (
  note, this seems to work better than my iPhone ).   In-call audio
  works for both incoming and outgoing calls, however I get no ringtone
  in the headset and as mentioned above, I can't answer or terminate the
  call.   I've verified on my iPhone6, that the headset works.  In
  addition to a ringtone in the earpiece, the headset also announces the
  incoming phone number.

  From looking at the ofono debug output, I'm never seeing a new HFP
  connection occur.  I noticed as the upower plugin uses a foreach_atom
  (HFP) style call to update the battery indicators on all attached HFP
  devices.

  I've tested this extensively on krillin, running rc-proposed:

  phablet@ubuntu-phablet:~$ system-image-cli -i
  current build number: 205
  device name: krillin
  channel: ubuntu-touch/rc-proposed/bq-aquaris.en

  version ubuntu: 20151216
  version device: 20151204-2254a36
  version custom: 2015--36-46-vivid

  I've also tested on mako, rc-proposed ( #317 ).

  For reference here's the versions of bluez, ofono, and PulseAudio on
  the device:

  bluez 5.36-0ubuntu2~overlay1
  ofono  1.17.bzr6908+15.04.20151203-0ubuntu1~awe3

[Kernel-packages] [Bug 1546310] Re: In CAR bluetooth not working

[Uranicus]

Dear all,

I have a new insight which might correlate to this bug or contribute to
the understanding. Maybe first of all, I just tested the above scenario
with:

current build number: 270
device name: krillin
channel: ubuntu-touch/rc-proposed/bq-aquaris.en
last update: 2016-03-01 15:29:28
version version: 270
version ubuntu: 20160301
version device: 20160108-efc96d8
version custom: 20160111-926-36—vivid

this issue is still the same. But I haven't expected it differently
since you seemed to be busy with other stuff.

Now the new insight:
-

I have had a similar issue with OTA9.1 but only in the following
circumstance: I start to call (and I establish this call fully) before I
start the bluetooth of my car. I have expected that the bluetooth of the
car picks this call up and I can continue with it via my car microphone
& speaker. But I ended with the same behaviour as described above (but
only in this circumstance with OTA9.1!):

I can not hear anything via my car speakers only if I turn on the phone
speaker (inner & outer speaker) I could hear it via these speakers. I
you want to have a look at these logs:

start of the call: 26.02.2016 at 18:38 h CET
start of the in car bluetooth system: approx. 18:42 h

I have verified this on later occasions again, this is a reproducible
situation for my phone/car/bluetooth combination.

  In CAR bluetooth not working

Bug description:
  I have paired my phone with my car as always (connection did work in
  the past). Connection runs as expected and everything like display,
  phone book, ... but this evening I wanted to place a call from my car
  and it did not work. I was then also not able to take a call (I could
  not hear the conterpart and the counterpart could not hear me).

  Since yesterday I am on:

  current build number: 259

  version custom: 20160111-926-36--vivid

  With OTA9 I did not have the issue. I have attached my logs. I have
  enabled the following bug-settings for bluetooth:

  sudo sed -i 's/exec \/usr\/sbin\/bluetoothd/exec
  \/usr\/sbin\/bluetoothd -d/g' /etc/init/bluetooth.conf

  sudo sed -i 's/--start/--start --log-level=debug/g'
  /usr/share/upstart/sessions/pulseaudio.conf

  I have modified the line in ofono.override to:

  exec ofonod -P -d provision,udev*,dun*,smart*,hfp_bluez5,stktest,sap

  I hope my reporting helps to trace down this issue.

  Backport more recent driver for SKL, KBL and BXT graphics

  Fix Committed

Bug description:
  We need to support Skylake (SKL), Kabylake (KBL) and Broxton (BXT)
  graphics in xenial, but the kernel driver is not fresh enough for
  proper support.

  For the kernel the plan is to provide a separate driver module
  (i915_bpo) like for Skylake/Broadwell/Braswell in vivid. The drm/i915
  driver in 4.4 is not recent enough for SKL/KBL/BXT, so pulling the
  driver from current drm-intel-next branch would provide what'll end up
  in 4.6. The i915 drivers will be modified so that only i915_bpo loads
  on SKL/KBL/BXT machines, and only there. The driver will get further
  updates along the way, and possibly also rebased to a later kernel
  release.

  Please backport Linux kernel upstream commit ID:


  commit 342300cc9cd3428bc6bfe5809bfcc1b9a0f06702

  Author: Martin Schwidefsky 

  Date:   Fri Feb 19 14:44:14 2016 +0100


  s390/compat: correct restore of high gprs on signal return


  git commit 8070361799ae1e3f4ef347bd10f0a508ac10acfb

  "s390: add support for vector extension"

  broke 31-bit compat processes in regard to signal handling.


  The restore_sigregs_ext32() function is used to restore the
  additional

  elements from the user space signal frame. Among the additional
  elements

  are the upper registers halves for 64-bit register support for
  31-bit

  processes. The copy_from_user that is used to retrieve the high-
  gprs

  array from the user stack uses an incorrect length, 8 bytes
  instead of

  64 bytes. This causes incorrect upper register halves to get
  loaded.

  Belkin Thunderbolt 2 Express Dock HD display port hot plug not
  supported.

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  There are two problems when using this dock:

  1. When booted, connecting the dock only allows USB and Ethernet to work, it 
does not support HDMI or DisplayPort monitors
  2. When booted with the device connected, while the device works fine, 
reseating the dock causes no adapters to work (No USB, Ethernet, HDMI and 
DisplayPort)

  This makes this dock and other Thunderbolt docks unusable, because I
  can't hotplug it correctly.

Bug description:
  We need to support Skylake (SKL), Kabylake (KBL) and Broxton (BXT)
  graphics in xenial, but the kernel driver is not fresh enough for
  proper support.

  For the kernel the plan is to provide a separate driver module
  (i915_bpo) like for Skylake/Broadwell/Braswell in vivid. The drm/i915
  driver in 4.4 is not recent enough for SKL/KBL/BXT, so pulling the
  driver from current drm-intel-next branch would provide what'll end up
  in 4.6. The i915 drivers will be modified so that only i915_bpo loads
  on SKL/KBL/BXT machines, and only there. The driver will get further
  updates along the way, and possibly also rebased to a later kernel
  release.

  With a C program sets FPE handler and triggers an FPE exception, it expects 
that machine-dependent context data, which is passed to the handler, will 
contain sensible values.

  In this scenario, however, FPC register was zero and contained no DXC
  (Data-Exception Code) indication:

  #include 
  #include 
  #include 

  void trapFunction() {
 asm volatile ("lhi %r1,0\n\t"
   "cit %r1,0,8\n\t");
  }

  static void sigFPE_handler(int signal, siginfo_t *info, void *context) {
 ucontext_t *uc = context;
 mcontext_t mc = uc->uc_mcontext;
 fpregset_t fpregs = mc.fpregs;
 unsigned int fpc = fpregs.fpc;

 printf("received signal!\n");
 printf("fpc: %08x\n", fpc );
  }

  int main() {
 struct sigaction action;
 memset(, '\0', sizeof(action));

 printf("registering signal handler\n");

 action.sa_flags |= SA_SIGINFO;
 action.sa_sigaction = sigFPE_handler;
 if (sigaction(SIGFPE, , NULL))
printf("error calling sigaction\n");

 printf("firing trap\n");
 trapFunction();
 return 0;
  }

  This program prints "fpc: ", but the expected output is "fpc:
  ff00"..

  The IBM Java team has encountered test failures around the use of trap
  instructions; Linux on z Distribution Test reproduced the issue on the
  following system:

  z13 LPAR
  Ubuntu 16.04
  Kernel 4.4.0-4-generic
  gcc (Ubuntu 5.3.1-8ubuntu2) 5.3.1 20160205
  libc6 2.21-0ubuntu5

  Also, similar issue has been found during test of SIMD (vector)
  instructions, FPC contents was also zero, whereas it expected at least
  an exception mask and vector-defined DXC.

[Kernel-packages] [Bug 1536810] Re: kernel install failed /bin/cp: cannot stat ‘/boot/initrd.img-4.3.0-7-generic’: No such file or directory

[Scott Moser]

Verified fixed in arm64 image for 20160227.
I noticed it does still have the bogus 'initrd.img file:
$ ls -l $exdir/boot
total 20592
drwxr-xr-x 2 root root 4096 Feb 27 14:36 grub
-rw-r--r-- 1 root root 21079648 Feb 27 14:38 initrd.img

But the initrd.img file does not seem to cause a problem  here, and after 
install we have a symlink to the proper place.
$ ls -l $exdir/boot/initrd.img
lrwxrwxrwx 1 root root 26 Mar  1 15:13 /tmp/tmp.RGUZJZwhWr/boot/initrd.img -> 
initrd.img-4.4.0-8-generic

I've reverted my workaround change in maas-images at revno 284.

  repeating phantom key when bt disconnects

Bug description:
  Every now and then when having bt mouse/keyboard connected - you will
  see when selecting a text box there is a repeating character (there is
  no specific character, but always repeats)

  It seems to be related somehow to bt devices disconnecting
  the only cure is a reboot

  This was reproduced by turning off the keyboard while holding down a
  key. We suspect the key up event is never delivered. This mimics the
  case where the BT connection drops off momentarily or perhaps an event
  is missed over the BT connection.

[Kernel-packages] [Bug 1551787] [NEW] Ubuntu crashed after Laptop is collapsed

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

After I collapsed the laptop, disconnected a monitor and took the laptop
to another place with a docking station and monitor, Ubuntu 15.10 was
not restartable again. It is a Thinkpad T440s. It was possible to change
keyboard lights via Fn + Space, but it was not possible to restart the
laptop by hitting any button or by hitting the power button. I only
could hit the power button for some seconds, so Ubuntu could restart. I
have no clue what package caused this.

[Kernel-packages] [Bug 1505564] Re: Soft lockup with "block nbdX: Attempted send on closed socket" spam

[Dan Streetman]

verification can be done with this script:


#!/bin/bash

modprobe nbd
qemu-nbd -d /dev/nbd0

truncate /tmp/testfile -s 20G
qemu-nbd -c /dev/nbd0 /tmp/testfile

for n in $( seq 1 250 ) ; do
  echo $n
  ( dd if=/dev/zero of=/dev/nbd0 bs=1 & )
done

qemu-nbd -d /dev/nbd0


after running that, on an unpatched system the dmesg will show a large number 
(~100 or more) of messages like:
[   70.408246] block nbd0: Attempted send on closed socket

with a patched kernel, the dmesg will show a ratelimited number (~10) of
those messages.

This has been verified on trusty 3.13, vivid 3.19, and wily 4.2

[Andreas Pokorny]

I will start with a small fix to get the repeat to stop on disconnect..
Then there still is a problem with modifier states that might be stuck untill 
the device is reattached and the key is pressed again..

  Canonical kernel team - please apply 1bc74f1ccd457832dc515fc1febe6655985fdcd2

  powerpc/powernv: Fix stale PE primary bus
  When PCI bus is unplugged during full hotplug for EEH recovery,
  the platform PE instance (struct pnv_ioda_pe) isn't released and
  it dereferences the stale PCI bus that has been released. It leads
  to kernel crash when referring to the stale PCI bus.

  This fixes the issue by correcting the PE's primary bus when it's
  oneline at plugging time, in pnv_pci_dma_bus_setup() which is to
  be called by pcibios_fixup_bus().

  Partially incorrect uid mapping with nfs4/idmapd/ldap-auth

Status in linux source package in Utopic:
  Fix Released
Status in nfs-utils package in Debian:
  Confirmed
Status in Fedora:

Bug description:
  [Impact]

   * This bug is likely to cause an incorrect UID/GID mapping for NFS
  shares in case of large numbers of differend UIDs/GIDs or in case of
  expired UID/GID mappings (stored as keys in the kernel).

  [Test Case]

   1. Setup a nfs4 server exporting /home with a large number of different 
users and ldap-based authentication.
   2. Mount the share on a ldap-connected client machine.
   3. List the mounted /home directory.
   4. Wait more than 10 minutes (the default key expiration time) and list it 
again with ls -l.

  Expected result - all directories are listed with correct UIDs/GIDs.
  Actual result - some of the directories may be listed with incorrect UID/GID 
of 4294967294.

  [Regression Potential]

   * This issue has been merged upstream in the 3.18 kernel and is also
  present in Debian's 3.16 kernel.

  [Other Info]

  * Original bug description:

  Partially incorrect uid mapping with nfs4/idmapd/ldap-auth

Status in linux source package in Utopic:

Status in nfs-utils package in Debian:

Status in Fedora:

Bug description:
  [Impact]

   * This bug is likely to cause an incorrect UID/GID mapping for NFS
  shares in case of large numbers of differend UIDs/GIDs or in case of
  expired UID/GID mappings (stored as keys in the kernel).

  [Test Case]

   1. Setup a nfs4 server exporting /home with a large number of different 
users and ldap-based authentication.
   2. Mount the share on a ldap-connected client machine.
   3. List the mounted /home directory.
   4. Wait more than 10 minutes (the default key expiration time) and list it 
again with ls -l.

  Expected result - all directories are listed with correct UIDs/GIDs.
  Actual result - some of the directories may be listed with incorrect UID/GID 
of 4294967294.

  [Regression Potential]

   * This issue has been merged upstream in the 3.18 kernel and is also
  present in Debian's 3.16 kernel.

  for  571 homedirs (this number varies at each reboot)/662, the owner is the 
value 4294967294. For the  91 remaining homedirs,
  the owner is correct. The gidnumber is correctly mapped for all (only  5 
differents values used for gidNumber).

  In /var/log/syslog, I can see :

  For example : user110 is mapped as 4294967294.
  but the command "id user110" returns :
  uid=31124(user110) gid=666(oldusers) groupes=666(oldusers)

  user110 logs in (auth ldap) from tty1. He runs "ls -l /home/user110/"

14.04.2 worked at some point, so what has changed ? The install failure
seems unrelated to the original bug.

Aaron Sosnick, in order to eliminate confusion, it will help immensely if you 
filed a new report (not reopen this one) with Ubuntu (not Mint) via a terminal:

  ACER Aspire 5100 laptop Suspend/Resume Failure

Status in linux package in Ubuntu:
  Invalid

Bug description:
  On this old laptop, Ubunutu 14.04 works fine on boot (after making
  sure fgrlx drivers are removed).

  However after a Suspend/Resume the screen flickers/tears so badly as to make 
the system unusable.
  Note that the problem does not occur with Hibernate/Resume. In fact if I can 
get the focus into a terminal while the
  screen is flickering and do a $ sudo pm_hibernate, the screen will be okay on 
Resume.

  Separately the wifi (b43) vanishes after a Resume, but I'll file a
  separate report on that later.

Title:
  LXD bootstrap issues on xenial

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm using lxd with zfs block storage on xenial, and having issues with
  trusty containers. I've witnessed this problem when trying to
  bootstrap as well as after rebooting the host and a container failed
  to start.

  In the latter case, the container that failed to start was the juju
  controller:

  I manually started it, but found that no upstart services were
  started. Remembering this thread,
  https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
  checked /var/log/mountall.log in the machine-0 container, and sure
  enough:

  root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat 
/var/log/upstart/mountall.log
  mount: permission denied
  mountall: mount /sys/kernel/debug [187] terminated with status 32
  mountall: Filesystem could not be mounted: /sys/kernel/debug

  The problem persists if I stop and start the container. If I remount
  /sys/kernel/debug on the host, then stop and start the container,
  upstart succeeds and the juju controller starts up.

  I manually started it, but found that no upstart services were
  started. Remembering this thread,
  https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
  checked /var/log/mountall.log in the machine-0 container, and sure
  enough:

  root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat 
/var/log/upstart/mountall.log
  mount: permission denied
  mountall: mount /sys/kernel/debug [187] terminated with status 32
  mountall: Filesystem could not be mounted: /sys/kernel/debug

  The problem persists if I stop and start the container. If I remount
  /sys/kernel/debug on the host, then stop and start the container,
  upstart succeeds and the juju controller starts up.

[Kernel-packages] [Bug 1551854] Re: LXD bootstrap issues on xenial

[Serge Hallyn]

I'm on the same kernel

Linux sl 4.4.0-8-generic #23-Ubuntu SMP Wed Feb 24 20:45:30 UTC 2016
x86_64 x86_64 x86_64 GNU/Linux

and also have the tracefs mounted

0 ✓ serge@sl ~ $ grep debug /proc/self/mountinfo
74 19 0:7 / /sys/kernel/debug rw,relatime shared:26 - debugfs debugfs rw
44 74 0:9 / /sys/kernel/debug/tracing rw,relatime shared:29 - tracefs tracefs rw

but trusty (upstart-based) containers start fine for me, using lxc
version 2.0.0~rc4+master~20160229-0647-0ubuntu1~xenial and lxd from git
HEAD.

Very odd therefore that unmounting and re-mounting debugfs works for
you...

Will try in a fresh vm.

  Ubuntu crashed after Laptop is collapsed

Bug description:
  After I collapsed the laptop, disconnected a monitor and took the
  laptop to another place with a docking station and monitor, Ubuntu
  15.10 was not restartable again. It is a Thinkpad T440s. It was
  possible to change keyboard lights via Fn + Space, but it was not
  possible to restart the laptop by hitting any button or by hitting the
  power button. I only could hit the power button for some seconds, so
  Ubuntu could restart. I have no clue what package caused this.

[Kernel-packages] [Bug 1333697] Re: ACER Aspire 5100 laptop Suspend/Resume Failure

[Aaron Sosnick]

This problem happens with or without Mint packages.

It is an Ubuntu problem and you are not nice for suggesting otherwise.

Please mark "won't fix" not invalid if that's your attitude.

I'll give some more recent Ubuntu versions a chance when I can and reopen
if it hasn't been fixed.

  ACER Aspire 5100 laptop Suspend/Resume Failure

Status in linux package in Ubuntu:
  Invalid

Bug description:
  On this old laptop, Ubunutu 14.04 works fine on boot (after making
  sure fgrlx drivers are removed).

  However after a Suspend/Resume the screen flickers/tears so badly as to make 
the system unusable.
  Note that the problem does not occur with Hibernate/Resume. In fact if I can 
get the focus into a terminal while the
  screen is flickering and do a $ sudo pm_hibernate, the screen will be okay on 
Resume.

  Separately the wifi (b43) vanishes after a Resume, but I'll file a
  separate report on that later.

[Kernel-packages] [Bug 1551854] Re: LXD bootstrap issues on xenial

[Casey Marshall]

I also confirmed that the mountall error message was duplicated every
time I restarted the machine-0 container -- until remounting on the
host.

Title:
  LXD bootstrap issues on xenial

Status in linux package in Ubuntu:
  New

Bug description:
  I'm using lxd with zfs block storage on xenial, and having issues with
  trusty containers. I've witnessed this problem when trying to
  bootstrap as well as after rebooting the host and a container failed
  to start.

  In the latter case, the container that failed to start was the juju
  controller:

  I manually started it, but found that no upstart services were
  started. Remembering this thread,
  https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
  checked /var/log/mountall.log in the machine-0 container, and sure
  enough:

  root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat 
/var/log/upstart/mountall.log
  mount: permission denied
  mountall: mount /sys/kernel/debug [187] terminated with status 32
  mountall: Filesystem could not be mounted: /sys/kernel/debug

  The problem persists if I stop and start the container. If I remount
  /sys/kernel/debug on the host, then stop and start the container,
  upstart succeeds and the juju controller starts up.

Title:
  Ubuntu crashed after Laptop is collapsed

Status in linux package in Ubuntu:
  New

Bug description:
  After I collapsed the laptop, disconnected a monitor and took the
  laptop to another place with a docking station and monitor, Ubuntu
  15.10 was not restartable again. It is a Thinkpad T440s. It was
  possible to change keyboard lights via Fn + Space, but it was not
  possible to restart the laptop by hitting any button or by hitting the
  power button. I only could hit the power button for some seconds, so
  Ubuntu could restart. I have no clue what package caused this.

  The first case:  "/dev/sde1" Partition is marked as bios-grub and should not 
be trying to be mounted by kernel.
  The second case " /dev/sdf1" is used by truecrypt application . Kernel should 
not be trying to mount it.

[Kernel-packages] [Bug 1551854] [NEW] LXD bootstrap issues on xenial

[Casey Marshall]

Public bug reported:

I'm using lxd with zfs block storage on xenial, and having issues with
trusty containers. I've witnessed this problem when trying to bootstrap
as well as after rebooting the host and a container failed to start.

In the latter case, the container that failed to start was the juju
controller:

I manually started it, but found that no upstart services were started.
Remembering this thread,
https://lists.ubuntu.com/archives/juju/2016-February/006698.html, I
checked /var/log/mountall.log in the machine-0 container, and sure
enough:

root@juju-5f4bd172-ad22-4726-8d84-47185ab31b54-machine-0:~# cat 
/var/log/upstart/mountall.log
mount: permission denied
mountall: mount /sys/kernel/debug [187] terminated with status 32
mountall: Filesystem could not be mounted: /sys/kernel/debug

The problem persists if I stop and start the container. If I remount
/sys/kernel/debug on the host, then stop and start the container,
upstart succeeds and the juju controller starts up.
