Title:
  text VTs are unavailable on desktop after upgrade to Ubuntu 17.10

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

Bug description:
  After upgrading my laptop to Ubuntu 17.10, I am unable to access
  gettys on any of the text-mode VTs on my system.

  gdm3 is running on VT1, my user session is running on VT2.  I can
  switch between these.  If I switch to VT3, I know that the VT switch
  has happened in the kernel because the X cursor disappears; but the
  display retains the output of my X session, and the text console with
  getty never appears.

  Switching back to VT2 works fine.

  The same problem occurs with either Wayland or X.

  My laptop is docked with an external monitor, which could be a factor.
  (I also notice that during boot, plymouth is only rendered on the
  internal monitor, not the external monitor; this may be related).  I
  have not yet tested whether this problem is reproducible if I undock.

  The system is booting with vt.handoff=7, which I believe is still the
  default in Ubuntu 17.10.

[Kernel-packages] [Bug 1589008] Re: Bluetooth freezing video playback In Ubuntu/Kubuntu 16.04

[Jason Gambrel]

I tried downgrading to 4.4.0-101-generic - no change

I tried adding the ppa ppa:ci-train-ppa-service/2685 and using sudo apt
update then sudo apt full-upgrade to upgrade bluez to 5.46 in Linux Mint
18.2 - this improved things a bit.  Less video freezing and able to
resume from freezing.

I tried editing /etc/pulse/default.pa and commenting out load-module 
module-suspend-on-idle:
### Automatically suspend sinks/sources that become idle for too long
#load-module module-suspend-on-idle

Source:
https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Bluetooth

This seems to have fixed the issue for me.

  Bluetooth freezing video playback In Ubuntu/Kubuntu 16.04

Bug description:
  In 16.04 when a bluetooth audio device is connected it freezes video
  playback and also no sound comes from online audio only streams. Issue
  does not exist with a wired headset.

  This issue does not exist with 15.10. All updates have been installed
  on 16.04 including backports but they have not fixed the issue.

  It is not browser specific and not website specific.

  It is not hardware specific as it affects my laptop with an intel 7260
  card and my pc with an intel 8260 card.

  The issue exists on both ubuntu and kubuntu 16.04.

  I have reported it on the ubuntu support forums and after
  investigation a moderator noticed changed in the kernel from 4.4 and
  4.2 that may becausing the issue and asked me to file a bug report.

[Kernel-packages] [Bug 1734172] Re: Upgrade ZFS to 0.7.3

[Richard Laager]

I have a related question... as far as I'm aware, the ZoL
kernel<->userspace interface is still not versioned:
https://github.com/zfsonlinux/zfs/issues/1290

Effectively, this means that the version of zfsutils-linux must always
match the version of the kernel modules. What is the plan to handle this
in Ubuntu's HWE kernels? For example, if Bionic gets ZFS 0.7.3, will
that show up in the Xenial HWE kernel? If so, that will create an
incompatibility, unless zfsutils-linux is updated in Xenial. But if
zfsutils-linux is updated in Xenial, then it will be incompatible with
the Xenial GA kernel.

[Kernel-packages] [Bug 1720930] Re: wlp3s0: failed to remove key (1, ff:ff:ff:ff:ff:ff) from hardware (-22)

[Hamid Alaei]

I had similar issue when switching to virtual terminals. Workaround #2 from #17 
works for me too.
I don't know if it is the expected behaviour, but now when I hit either 
ctrl+alt+F1 and ctr+alt+f2, the same graphical interface (not text consoles) 
will appear.

  Bluetooth and Wifi: coexistence Problem

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Triaged

Bug description:
  I'm currently running kernel 4.13.0-12 on Ubuntu 17.10 (daily) and
  have noticed that with my Intel Corporation Wireless 8260 (rev 3a)
  there appears to be a problem with buetooth and wifi coexistence.

  Unless I disable bluetooth and/or wifi I am unable to connect to the
  opposite to which I have disabled.

  Adding:

  options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8

  To:

  /etc/modprobe.d/iwlwifi.conf

  Solve the problem. This is a reversion to less functionality as on
  earlier kernels (default kernel on 17.04) this did not occur.

  This would appear to be a problem that has previously been identified
  with earlier versions of the Intel hardware (see
  https://wiki.debian.org/iwlwifi#Troubleshooting) but not with the
  8260.

Bug description:
  [SRU sysdig XENIAL for 4.11 and 4.13 kernel support]

  sysdig DKMS fails to build because of API changes in 4.11, 4.13

  [FIX]

  Apply the following upstream sysdig commits for various kernel compat
  fixes:

  - [5fef96] Fix for kernel < 3.9 with CPU_ACCOUNTING_NATIVE disabled.
  - [29c40f] Fix cputime for kernel 3.8 and 2.6.18
  - [4596f0] Make sure to unlock mutex during error paths
  - [460f6e] Update probe module for kernel 4.11 (#829)

  [TEST]
  from kernel team autotests:

  sudo autotest/client/autotest-local
  autotest/client/tests/ubuntu_sysdig_smoke_test/control

  Without the fixes, these will fail. With the fixes, the regression
  tests pass. Run this 4.4, 4.8, 4.11 azure and 4.13-hwe kernels, must
  pass on all three kernel versions.

  [REGRESSION POTENTIAL]
  This affects just the sysdig driver. Could break on pre-4.13 older kernels, 
so needs regression checking on supported kernel versions.

[Kernel-packages] [Bug 1729573] Re: netplan breaks Xen VIF driver

[Łukasz Zemczak]

Hello Dan, or anyone else affected,

Accepted nplan into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/nplan/0.32~16.04.1 in
a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-xenial to verification-done-xenial. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-xenial. In either case, details of your
testing will help us make a better decision.

Further information regarding the verification process can be found at

Bug description:
  [Impact]

  Some network interfaces on a Xen guest are broken by new behavior
  introduced by netplan.  On a Xen guest instance, when netplan is run
  to 'apply' its configuration, under certain circumstances netplan will
  try to "reset" the interface by unbinding and then re-binding the
  interface driver from the interface, by using the sysfs "bind" and
  "unbind" functions of the driver.  Normally, this results in the
  interface being released and then fully re-initialized by the driver.

  However the Xen VIF driver breaks when this is done.  The internal Xen
  backend state of the interface remains in 'closed' state after the
  driver re-connects to the interface, and attempts to open and use the
  interface result in a kernel Oops in the Xen VIF driver.

  To users, it appears that the interface is unusable because it has an
  all 0 mac address; but if the mac is manually set and the interface
  brought up the driver Oopses as mentioned above.

  This problem makes booting painful because of very long timeouts
  waiting for all network interfaces to start, and affected Xen VIF
  interfaces will of course never complete startup.

  [Fix]

  No fix yet.  Upstream kernel does not appear fixed.

  [Test Case]

  Create a guest instance under a Xen hypervisor (e.g. an AWS instance)
  that has Ubuntu Artful 17.10 installed.  Use only a single interface
  at first when creating it.  Then once it is ready, attach a second
  network interface to the instance.  From inside the instance,
  configure the new interface in netplan (i.e. add a /etc/netplan/
  config for it).  Make sure the new interface is down (netplan does not
  appear to unbind/bind interfaces that are up), and then run:

  $ sudo netplan apply

  or for debug,

  $ sudo netplan --debug apply

  this will unbind and re-bind the second interface, which will then
  have all-0 mac, and will be unusable, as described above.

  [Regression Potential]

  Changes to the Xen VIF driver can result in unusable network
  interfaces, or problems while using Xen VIF interfaces.

  [Other Info]

  Problem appears to exist upstream also.

[Kernel-packages] [Bug 1730717] Re: Some VMs fail to reboot with "watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [systemd:1]"

[Iain Lane]

Just a heads up - this apparently became much harder for me to reproduce
at will. We're still seeing it in actual workloads but I'm having
trouble recreating manually.

My current strategy is to start stress-ng on a number of machines and
then constantly reboot them, with the idea that this will stress the
cloud and make the bug more likely, which relies on the assumption that
this bug is somehow to do with busyness on the underlying machines.

  This is impacting us for ubuntu autopkgtests. Eventually the whole

  and backs off until the next reset (6 hourly).

  17.10 (and bionic) guests are sometimes failing to reboot. When this
  happens, you see the following in the console

  One host that exhibits this behaviour was:

    Linux klock 4.4.0-98-generic #121-Ubuntu SMP Tue Oct 10 14:24:03 UTC
  2017 x86_64 x86_64 x86_64 GNU/Linux

  guest running:

    Linux version 4.13.0-16-generic (buildd@lcy01-02) (gcc version 7.2.0
  (Ubuntu 7.2.0-8ubuntu2)) #19-Ubuntu SMP Wed Oct 11 18:35:14 UTC 2017
  (Ubuntu 4.13.0-16.19-generic 4.13.4)

  The affected cloud region is running the xenial/Ocata cloud archive,
  so the version of qemu-kvm in there may also be relevant.

  Here's how I reproduced it in lcy01:

    $ for n in {1..30}; do nova boot --flavor m1.small --image 
ubuntu/ubuntu-artful-17.10-amd64-server-20171026.1-disk1.img --key-name 
testbed-`hostname` --nic net-name=net_ues_proposed_migration laney-test${n}; 
done
    $  sudo reboot
    # wait a minute or so for the instances to all reboot
    $ for n in {1..30}; do echo "=== ${n} ==="; nova console-log laney-test${n} 
| tail; done

  On bad instances you'll see the "soft lockup" message - on good it'll
  reboot as normal.

  We've seen good and bad instances on multiple compute hosts - it
  doesn't feel to me like a host problem but rather a race condition
  somewhere that's somehow either triggered or triggered much more often
  by what lcy01 is running. I always saw this on the first reboot -
  never on first boot, and never on n>1th boot. (But if it's a race then
  that might not mean much.)

  I'll attach a bad and a good console-log for reference.

  If you're at Canonical then see internal rt #107135 for some other
  details.

kernels,
I will write again, I dont wanna lose my working OS to the new mainline
builds.

I plan to upgrade to 17.10 soon, but I got the newest KDE software working
on 17.04.
All the best

  Steps:
  1. Run the ubuntu_stress_smoke_test
  2. Try to remove everything in ~/autotest/client/tmp/

  After the stress smoke test, an unremovable inode flag fill will be created 
in the temp directory:
  
~/autotest/client/tmp/ubuntu_stress_smoke_test/src/stress-ng/tmp-stress-ng-inode-flags-248463-2

  # lsattr
  -uS-ie-- ./stress-ng-inode-flags-248463-2-1540465499

  On s390x instances, instead of re-deploying it, we will ask jenkins to remove 
the tmp directory.
  Therefore this issue will cause the test to fail.

  The solution for now is to run chattr -i on that file, so it can be
  removed.

[Kernel-packages] [Bug 1703742] Re: Transparent hugepages should default to enabled=madvise

[Colin Ian King]

** Description changed:

+ SRU Justification, Zesty, Xenial
+ 
+ [Impact]
+ 
  Ubuntu kernels should default transparent_hugepages to enabled=madvise,
  not enabled=always
  
  (this corresponds to TRANSPARENT_HUGEPAGE_MADVISE=y in .config).
  
  I've blogged about this at some length here:
  https://blog.nelhage.com/post/transparent-hugepages/ but here is a
  summary:
  
  Transparent Hugepages are a feature that allows the kernel to attempt to
  automatically back any anonymous maps with "huge" 2MiB page tables,
  instead of the normal 4k entries. It can produce small net performance
  gains in certain benchmarks, but also has numerous downsides, in the
  form of apparent memory leaks and 30% slowdowns or worse for some
  applications. Many popular pieces of software now refuse to run with
  hugepages enabled because of known performance issues.
  
  Examples of problem reports:

  Oracle:

  Setting `enabled=madvise` enables applications that know they benefit
  from transparent huge pages to opt-in to this feature, while eliminating
  all the problematic behavior for other applications. Note also that
  transparent hugepage settings don't affect the use of explicit hugepages
  via hugetlbfs or mmap(…, MAP_HUGETLB, …)
+ 
+ [Fix]
+ Enable CONFIG_TRANSPARENT_HUGEPAGE_MADVISE=y
+ 
+ [Regression Potential]
+ May marginally impact performance, but the benefits of madvise'd huge 
transparent hugepage over-weigh this considerably.
+

[Kernel-packages] [Bug 1733864] Re: kernel 4.10.0-40 is hanging with a CPU soft lock

[Kleber Sacilotto de Souza]

The problem seems to be related to how qemu allocates the virtual cores
and threads to the VM.

Starting the VMs with the following command I cannot reproduce the
issue:

$ qemu-system-ppc64le -m 1024 -smp 16,threads=8 -nographic -net
nic,model=virtio -net user,hostfwd=tcp::10022-:22 -drive file
=./autopkgtest-xenial-ppc64el.img -enable-kvm

As long the number of cpus and threads provided to the -smp parameter
follow the topology of the p8 processor, making qemu use more than one
core only if the number of threads is multiple of 8, I can't reproduce
the hang. If the parameters provided makes qemu spread the virtual
threads on more than one physical cpu without using all the 8 threads
(e.g. '-smp 2', '-smp 4,threads=2', '-smp 8,threads=4') then the guest
kernel hangs at some point.

This is the environment being tested:

Machine type-model: 8247-22L

Host: Artful
kernel 4.13.0-17-generic
qemu 2.10+dfsg-0ubuntu3

Guests: Xenial, Zesty and Artful with latest kernel from -updates.

Could someone from IBM please confirm if this is a known or expected
behavior? This issue seems to be around for a long time and it's odd
that this hasn't come up before.

  17.10 - suspend/resume failure

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I'm experiencing a failure in the resume process after the suspend.
  When I try to resume the system start, but the screen stay black while
  the disk seem be really busy.

  The only way to exit from this status is unplug the system before

[Kernel-packages] [Bug 1734038] Re: Potential regression found with apparmor test on Xenial/Zesty

[Andy Whitcroft]

Ok this seems to be an issue with some of the basic apparmor commands
not preprocessing the profiles when working on them.

If we ask apparmor to parse the file in question it is happy to do so:

apparmor_parser -p -Q /etc/apparmor.d/snap.core.3440.usr.lib.snapd.snap-confine
[...]
# Those are discussed on 
https://forum.snapcraft.io/t/snapd-vs-upstream-kernel-vs-apparmor
# and https://forum.snapcraft.io/t/snaps-and-nfs-home/
 

##included "/var/lib/snapd/apparmor/snap-confine.d"


# We run privileged, so be fanatical about what we include and don't use
# any abstractions
/etc/ld.so.cache r,
[...]

However, it does not seem to handle this well when we use some of the
associated utilities:

$ sudo aa-complain foo

ERROR: Syntax Error: Unknown line found in file 
/etc/apparmor.d/snap.core.3440.usr.lib.snapd.snap-confine line 15:
include "/var/lib/snapd/apparmor/snap-confine.d"   /etc/ld.so.cache r,

$ sudo aa-disable foo

[Kernel-packages] [Bug 1594023] Re: Poweroff or reboot hangs. Laptop won't shutdown. 16.04

I got the same problem on a Lonovo ideapad 100. 
Installed via standard update manager kernel 4.4.x and the problem was solved.

Title:
  Poweroff or reboot hangs. Laptop won't shutdown. 16.04

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  This is about a fresh Ubuntu 16.04 install on a new laptop (asus
  x540sa). After pressing the shutdown button in the start menu; the
  shutdown procedure starts and in the final splash screen the system
  just hangs. Tried a second time by pressing Esc once the splash screen
  showed up and I saw that it reaches the line "Reached target shutdown"
  and just stops there, no matter how long I leave it there the machine
  won't turn off.

  I also tried a Kubuntu 16.04 fresh install on the same machine and it
  hanged too at the final splash screen where the pulsating logo
  stopped. Then I tried with Esc only to see the exact same line in the
  end.

  The issue seems to affect lately quite many users as shown by the
  google results of the past month / week or so.

  I have also tried shutting down from the console with shutdown -and
  all the parameters after that suggested online- and sudo poweroff but
  unfortunately they didn't do the trick. The exact same situation
  occurred.

  Unmounting the swap as suggested online doesn't work.

  Also rebooting the system is not working either due to the same issue.

  So right now the only way for me to poweroff the machine is to press
  the power button on the keyboard continuously.

  Reproducible: Always

  Steps to Reproduce:
  1.Install OS
  2.Do something, anything or nothing
  3.Try to shutdown or reboot

  Actual Results:
  The computer is not shutting down: "Reached target shutdown" and hangs there.

  Expected Results:
  Powering off the machine.

  For what it's worth, closing the lid won't suspend the system, but
  using the menu buttons for suspension will do it.

Title:
  Potential regression found with apparmor test on Xenial/Zesty

Status in linux package in Ubuntu:
  Incomplete
Status in snapd package in Ubuntu:
  New

Bug description:
  Issue found with Xenial kernel 4.4.0-102 and Zesty kernel 4.10.0-41,
  across different architectures

  Multiple tests from ubuntu_qrt_apparmor test suite failed with the same error 
message:

  (BTW the include and this ld.so.cache are not in the same line, please
  refer to comment #3 for attachment)

  This issue will gone if you downgrade the snapd and ubuntu-core-launcher

[Kernel-packages] [Bug 1730924] Re: Wifi does down "crash" in Surface Pro 4

[Hicks]

At the moment the wifi has not fallen, but after a reboot of the system has 
been slow enough to start and gives me this error.
I'll keep trying to see if he can hold on.

[Kernel-packages] [Bug 1637754] [NEW] No image out of display port in Lenovo T460s

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I've tried to connect my Lenovo T460s to a HDMI projector using a mini
display port to HDMI cable. Although this works in windows on the same
hardware, on linux nothing is displayed and the projector says "No
signal". Ubuntu recognizes the projector and sets everything up in the
Displays settings though.

[Kernel-packages] [Bug 1734038] Re: Potential regression found with apparmor test on Xenial/Zesty

[Michael Vogt]

We believe this is a kernel/apparmor issue. The apparmor documentation
(http://wiki.apparmor.net/index.php/AppArmor_Core_Policy_Reference#Include_statements)
lists "include" as a valid include. We are happy to fix snapd but I'm
sure there a many existing profiles (beside snapd from other packages or
user written ones) that will break if this change lands.

Title:
  cpupower suggests installation of non-existent linux-cloud-tools-
  generic package

Status in The Ubuntu-power-systems project:
  Invalid
Status in linux package in Ubuntu:
  Invalid

Bug description:
  Problem Description
  ===
  cpupower suggests installation of non-existent linux-cloud-tools-generic 
package

  Problem occurs on an IBM POWER 16.04 LTS system. Unknown whether it
  occurs on other architectures or later releases.

  When run _without package "linux-tools-$(uname -r)" installed_,
  cpupower will issue a complaint, suggesting to install (among others),
  some linux-cloud-tools-*-generic packages:

  $ cpupower
  WARNING: cpupower not found for kernel 4.4.0-75

You may need to install the following packages for this specific kernel:
  linux-tools-4.4.0-75-generic
  linux-cloud-tools-4.4.0-75-generic

You may also want to install one of the following packages to keep up to 
date:
  linux-tools-generic
  linux-cloud-tools-generic

  However, those linux-cloud-tools-*-generic package appear not to exist
  --at least not in the default repos.

  Package linux-cloud-tools-common exists, but none of the *-generic
  packages are available:

  $ apt-cache policy "linux-cloud-*"
  $ cat xxx
  linux-cloud-tools-common:
Installed: (none)
Candidate: 4.4.0-78.99
Version table:
   4.4.0-78.99 500

   4.4.0-21.37 500
  500 http://us.ports.ubuntu.com/ubuntu-ports xenial/main ppc64el 
Packages

  
  The cpupower command works (at least doesn't give this complaint) if the 
appropriate linux-tools-$(uname -r) (perhaps via linux-tools-generic) is 
installed, so the cloud package is maybe not needed (as least for some 
functionality).

  I think the fix is to either: 
  a) supply the cloud packages for POWER, or 
  b) remove the non-existent packages from cpupower's complaint message.
   
  ---uname output---
  Linux fs3 4.4.0-75-generic #96-Ubuntu SMP Thu Apr 20 09:55:30 UTC 2017 
ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = Firestone 
   
  ---Steps to Reproduce---
   Install linux-tools-common but NOT linux-tools-*-generic on a POWER 16.04 
LTS system, then run cpupower.

  Userspace rpm: linux-tools-common

Title:
  text VTs are unavailable on desktop after upgrade to Ubuntu 17.10

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

Bug description:
  After upgrading my laptop to Ubuntu 17.10, I am unable to access
  gettys on any of the text-mode VTs on my system.

  gdm3 is running on VT1, my user session is running on VT2.  I can
  switch between these.  If I switch to VT3, I know that the VT switch
  has happened in the kernel because the X cursor disappears; but the
  display retains the output of my X session, and the text console with
  getty never appears.

  Switching back to VT2 works fine.

  The same problem occurs with either Wayland or X.

  My laptop is docked with an external monitor, which could be a factor.
  (I also notice that during boot, plymouth is only rendered on the
  internal monitor, not the external monitor; this may be related).  I
  have not yet tested whether this problem is reproducible if I undock.

  The system is booting with vt.handoff=7, which I believe is still the
  default in Ubuntu 17.10.
