[Kernel-packages] [Bug 1561830] Re: Hard disk writes fail in 16.04 daily on nForce 430

[Stephen Worthington]

I would be happy to try a mainline kernel, but I am getting this problem
when trying to install Ubuntu 16.04 daily from a live install DVD.  So
is there any way to get a mainline kernel into the live DVD, so I can
run it from there?  Alternatively, I can reinstall Ubuntu 15.10 and try
it there, if that would work.  I would also need to try a kernel that
did have the problem with Ubuntu 15.10, to properly verify the 4.5
kernel fixed it, so what kernel would I need to try for that?

Title:
  Hard disk writes fail in 16.04 daily on nForce 430

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have an old PC I use for testing new operating systems.  It has
  previously had Ubuntu 15.10 installed and working.  The motherboard is
  an Asus M2NPV-VM, with Nvidia nForce 430 chipset and Nvidia GeForce
  6150 GPU.  I have installed an Nvidia GT220 card to use for more
  modern video support.

  When I attempt to install Ubuntu 16.04 beta (daily xenial-desktop-
  amd64.iso file downloaded 24/03/2016  18:17), it starts to write to
  the hard disk (Samsung HD103UJ), and after a short time the install
  got lots of disk write errors in kern.log.  After the errors, the disk
  was unable to be read either, with "fdisk -l /dev/sda" failing to read
  a sector, where it had worked before starting the install.  Unplugging
  the SATA cable to the drive and plugging it in again made the drive
  work again (on /dev/sdc), but another attempt to install failed with
  the same write errors.

  I noticed that the log had swap write errors also, so I rebooted the
  install DVD again, and this time did a "swapoff -a" command before
  attempting to install, but got the same errors again.  So I found my
  Ubuntu 15.10 install DVD and tried a new install from that, which
  worked just fine.

  On rebooting with my 16.04 daily DVD, I again did "swapoff -a" so that
  the DVD based system would run normally, then tried mounting the EXT4
  system partition I had just installed using the 15.10 install DVD.
  That worked, so I tried dd commands to do test writes to that
  partition.  The following commands worked:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=10k
dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=100k

  but when I did this command:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=1000k

  after a while errors started appearing in kern.log, just as with the
  attempts to install 16.04.

  It appears that with sustained write activity, the errors will start
  and then the drive will become unusable until it is unplugged and
  plugged in again.

  I have attached the kern.log and syslog files from the 15.10 install
  that worked, and the 16.04 install attempt that failed.  The first
  error message appears to be this:

  ata3: EH in SWNCQ mode,QC:qc_active 0x1FFF sactive 0x1FFF
  ata3: SWNCQ:qc_active 0x1 defer_bits 0x1FFE last_issue_tag 0x0
  dhfis 0x1 dmafis 0x0 sdbfis 0x0

  which leads me to suspect a problem with the handling of the SATA 
controller's interrupts.

Title:
  Screen icons and text corrupted after 15.10 upgrade

Status in linux package in Ubuntu:
  Expired

Bug description:
  Since upgrading to 15.10 I am having trouble with most of the desktop
  and other icons and some text. The problem seems to be that the screen
  painting lines are out of synch.

  This means that most of the icons on the desktop are almost unreadable
  and spread laterally. Also PDF documents are unreadable. The raster
  graphics that I have imported into Inkscape are unusable.

  I am using a Dell Vostro 220 and Dell screens. The affect is the same
  whether I use a wide screen or a more conventional profile.

Title:
  lockup when using DVI and display port with skylake

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When using dual monitors, one connected to the dvi port, and one connected to 
the display port,
  and when nxclient 3.5.0-7 is running, the kernel will lock up about once a 
day, sometimes more often.

  after it has locked up, the mouse cursor doesn't move, caps lock doesn't 
toggle the keyboard light, the pc can't be pinged,
  there is nothing written in the logs about the crash.

  If nxclient isn't running, it doesn't lock up. I don't think it has
  locked up since switching to vga and dvi.

  I believe this is a skylake problem. I'm able to help test and debug
  if required and given instructions.

[Kernel-packages] [Bug 1563146] [NEW] lockup when using DVI and display port with skylake

[Michael Chesterton]

Public bug reported:

When using dual monitors, one connected to the dvi port, and one connected to 
the display port,
and when nxclient 3.5.0-7 is running, the kernel will lock up about once a day, 
sometimes more often.

after it has locked up, the mouse cursor doesn't move, caps lock doesn't toggle 
the keyboard light, the pc can't be pinged,
there is nothing written in the logs about the crash.

If nxclient isn't running, it doesn't lock up. I don't think it has
locked up since switching to vga and dvi.

I believe this is a skylake problem. I'm able to help test and debug if
required and given instructions.

[Kernel-packages] [Bug 1528101] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From pt...@cn.ibm.com 2016-03-28 21:29 EDT---
Hi,

This bug only occurs when min_free_kbytes=312721 is written in
/etc/sysctl.conf. If we didn't write it into /etc/sysctl.conf and just
set it with "sysctl min_free_kbytes=312721", then this bug won't be
triggered when triggering kdump.

  Yes, I just found that if use the default min_free_kbytes value then

Bug description:
  This is a clone from bug 1505564, to track the separate issue of the
  serial port driver failing to schedule itself off its cpu.

  The original bug's problem was caused by the kernel spamming a huge
  number of error messages in a certain situation.  Normally, that would
  not be a problem, but in this case the system is virtualized, and logs
  over its serial port.  When the massive number of kernel messages are
  sent to the serial port driver, it can't keep up, so sending all the
  log messages can take a very long time - minutes or longer - and the
  serial port driver fails to schedule itself off the cpu it's using
  during that time.  That results in other cpus hanging, waiting for the
  serial port driver's cpu to become avaiable.

  I'll  update the bug with more details as I debug.

  "Candy"

Status in linux package in Ubuntu:

Bug description:
  Upon successful installation of Ubuntu 15.10, I ran the usual updates
  and after restarting, the touchpad stopped working.

  I booted into kernel version 4.2.0-16 instead of the updated kernel
  4.2.0-34, and the touchpad that had stopped working functioned as
  usual once more. Changing back into the latest kernel disabled the
  touchpad once more.

  I am installing Ubuntu on the Dell Chromebook 11 "Candy" running Intel
  Celeron(R) CPU N2840 (Baytrail) processor. This deployment is being
  used for several lab machines of the same model.

  Steps to reproduce:

  1. Install Ubuntu 15.10.
  2. Run update.

  Expected:

  1. All hardware to work prior to update.

  Instead:

  1. Touchpad stopped working.

  Patch 1 sends a link reset for port1 following a login timeout error. This 
same fix was delivered previously for port0.

  Patch 2 provides feedback to applications so that they may know when
  it is acceptable to perform an I/O retry for a virtual LUN.

  == Comment: #5 - Matthew R. Ochs  - 2015-11-04 16:25:54 ==
  These patches are not yet upstreamed but will be as part of the 4.4 'rc' 
phase.

Title:
  Touchpad stopped functioning after kernel update for Dell Chromebook
  "Candy"

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Upon successful installation of Ubuntu 15.10, I ran the usual updates
  and after restarting, the touchpad stopped working.

  I booted into kernel version 4.2.0-16 instead of the updated kernel
  4.2.0-34, and the touchpad that had stopped working functioned as
  usual once more. Changing back into the latest kernel disabled the
  touchpad once more.

  I am installing Ubuntu on the Dell Chromebook 11 "Candy" running Intel
  Celeron(R) CPU N2840 (Baytrail) processor. This deployment is being
  used for several lab machines of the same model.

  Steps to reproduce:

  1. Install Ubuntu 15.10.
  2. Run update.

  Expected:

  1. All hardware to work prior to update.

  Instead:

  1. Touchpad stopped working.

[Kernel-packages] [Bug 1562540] Re: kernel 3.13.0-83 regression : screen resolution not detected

[Joseph Salisbury]

I built a -proposed Trusty test kernel.  It is based on the upstream
3.13.0-ckt36 updates.  This kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1562540/

Note, with this test kernel, both the linux-image and linux-image-extra
.debs are needed.

[Kernel-packages] [Bug 1562989] Re: 'aa_change_onexec failed with -1. errmsg: Permission denied'

Looks like the kernel got some fixes and the rules for change_profile
matching unconfined that we had for the launcher no longer work. Those
rules seem like they weren't doing what we wanted anyway, so update
them.

  The hello-world app works ok (it needs ubuntu-core-launcher 1.0.20 since it 
gets past the above error and the launcher needs to account for NO_NEW_PRIVS):
  $ hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  $ sudo /snaps/bin/hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  cap-test.mvo doesn't have this problem either:
  $ sudo snappy install cap-test.mvo
  $ cap-test.xbomb

  If I disable the apparmor profile with: sudo apparmor_parser -R
  /etc/apparmor.d/usr.bin.ubuntu-core-launcher then the app will launch.

  Downgrading to the -13 kernel resolves the issue:
  $ cat /proc/version_signature
  Ubuntu 4.4.0-13.29-generic 4.4.5

Re: [Kernel-packages] [Bug 1556362] Re: Graphic display problem

[Jonathan Tigner]

Hi Christopher,
I tried version 16.04 after following the link below and installing 
xenial-desktop-i386.iso on a memory stick.  The first try, it didn't recognize 
my screen so I re-installed it and tried again.  It worked fine, but Firefox 
seemed to have a few bugs as it would not load a script and so I ended up 
re-starting it because I couldn't get it to respond.  Then it worked fine until 
it went to black and  white.  The B mode almost seemed like a power saving 
feature and the screen would go back to colour once in a while.  As I am 
writing this, I am back to v15.1.
I don't know how you would like this written up or what information you would 
like.  I can live with the occasional wonky screen if need be as it seems to 
self-correct if I switch to another application and then back.  Still, 
something funny is going on.  Perhaps it is a problem with my PC. - I used a 
toshiba system check tool and it seemed to indicate everything was okay.
Please let me know if you want me to pursue this further.
Thanks,
Jonathan

[Kernel-packages] [Bug 1563039] [NEW] VM fails to restart after instalation of Ubuntu Desktop amd64 in Xenial Daily

[Adam Sims]

Public bug reported:

Installation followed as per test case on Xenial Daily:
http://iso.qa.ubuntu.com/qatracker/milestones/351/builds/115697/testcases/1300/results

Virtualbox completes installation and requests use restarts system.

User clicks restart.

System shut-down begins.

System hangs and restart does not complete: See attached screen-shot.

Virtualbox system is running on 2048mb RAM, 2 cores CPU.

Due to the time in which this bug occurs, I am unsure as how to provide
additional information, but I hope this is helpful for any future
reference or similar occurrences.

** Affects: linux (Ubuntu)

[Kernel-packages] [Bug 1562989] Re: 'aa_change_onexec failed with -1. errmsg: Permission denied'

[Jamie Strandboge]

It appears that the profile name can't start with 'u'. If I change the
app-profile to prepend anything other than 'u', then it works.

Eg, if I update app-profile accordingly before each call to change the profile 
name:
$ sudo apparmor_parser -r ./app-profile ./launcher-profile && aa-exec -p 
launcher -- ./test-1562989 ubuntu-clock-app.ubuntucoredev_clock_3.6+snap2 
/usr/bin/uptime
argv[0]: ./test-1562989
argv[1]: ubuntu-clock-app.ubuntucoredev_clock_3.6+snap2
argv[2]: /usr/bin/uptime
aa_change_onexec failed with -1. errmsg: Permission denied

$ sudo apparmor_parser -r ./app-profile ./launcher-profile && aa-exec -p 
launcher -- ./test-1562989 u /usr/bin/uptimeargv[0]: ./test-1562989
argv[1]: u
argv[2]: /usr/bin/uptime
aa_change_onexec failed with -1. errmsg: Permission denied

$ sudo apparmor_parser -r ./app-profile ./launcher-profile && aa-exec -p 
launcher -- ./test-1562989 fooubuntu-clock-app.ubuntucoredev_clock_3.6+snap2 
/usr/bin/uptime

argv[2]: /usr/bin/uptime
 15:40:27 up 18 min,  2 users,  load average: 0.02, 0.10, 0.08

Wild guess would be the check for unconfined is busted.

  $ sudo snappy install ubuntu-clock-app.ubuntucore-dev
  $ ubuntu-clock-app.clock
  aa_change_onexec failed with -1. errmsg: Permission denied
  [1]

  There is an apparmor denial:
  audit: type=1400 audit(1459194964.529:35): apparmor="DENIED" 
operation="change_onexec" profile="/usr/bin/ubuntu-core-launcher"

comm="ubuntu-core-lau" target="ubuntu-clock-app.ubuntucoredev_clock_3.6+snap2"

  Downgrading to ubuntu-core-launcher doesn't help the clock app get
  past this failure.

  The hello-world app works ok (it needs ubuntu-core-launcher 1.0.20 since it 
gets past the above error and the launcher needs to account for NO_NEW_PRIVS):
  $ hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  $ sudo /snaps/bin/hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  cap-test.mvo doesn't have this problem either:
  $ sudo snappy install cap-test.mvo
  $ cap-test.xbomb

  If I disable the apparmor profile with: sudo apparmor_parser -R
  /etc/apparmor.d/usr.bin.ubuntu-core-launcher then the app will launch.

  Downgrading to the -13 kernel resolves the issue:
  $ cat /proc/version_signature

[Kernel-packages] [Bug 1542862] Re: pl2303h and ftdi serial port bug

[Jason Curl]

While I haven't been able to set up another Ubuntu installation just
yet, I did need to reinstall something for production and updated to
Ubuntu 16.04 (Dev branch) x64 and I confirm that the bug is still there
(same machine as in the original problem report).

  pl2303h and ftdi serial port bug

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  When developing an application using serial ports, behaviour between
  process restarts is undefined for particular usb serial port chipsets.

  Tested chipsets to fail are:
  * pl2303H
  * ftdi

  Tested chipsets to work are:
  * 16550A
  * pl2303ra

  Attached is a minimal test program to recreate the issue. The program
  needs to run twice, the first to create the problem, the second
  instance that shows the problem. See the comments at the beginning of
  the test program to see expected output and observed output.

  You'll need the device under question attached and running as the
  receiver in the test program and a NULL modem cable (3 wire). Easiest
  to show the problem if you have two of the same USB devices attached
  and execute the command with "./a.out /dev/ttyUSB0 /dev/ttyUSB1".

  Note, flushing, and other workarounds haven't worked, only physically
  removing and reinserting the problematic devices between runs (in
  particular, the device that is receiving the data over the serial
  port).

  As there appears to be data in a buffer between runs that can't be
  properly flushed, I can't say if this is a potential security issue or
  not.

  == Comment: #0 - Hendrik Brueckner - 2016-03-15 06:33:03 ==
  For NUMA, ensure the setting of these kernel configuration for s390x:

  # CONFIG_NUMA_BALANCING_DEFAULT_ENABLED is not set
  CONFIG_NUMA_EMU=y
  CONFIG_EMU_SIZE=0x1000

  
  CONFIG_NUMA without CONFIG_NUMA_EMU does not make any sense. s390 does not 
provide hardware topology information. However, we do support fake NUMA to 
improve performance issues seen with very large memory configurations. 
Therefore, CONFIG_NUMA_EMU has to be enabled.

  Given that we only support fake NUMA
  CONFIG_NUMA_BALANCING_DEFAULT_ENABLED should be disabled, since it
  moves pages without any benefit but costs additional cpu cycles.

  'aa_change_onexec failed with -1. errmsg: Permission denied'

Status in linux package in Ubuntu:
  Confirmed

  $ sudo snappy install ubuntu-clock-app.ubuntucore-dev
  $ ubuntu-clock-app.clock
  aa_change_onexec failed with -1. errmsg: Permission denied
  [1]

  There is an apparmor denial:
  audit: type=1400 audit(1459194964.529:35): apparmor="DENIED" 
operation="change_onexec" profile="/usr/bin/ubuntu-core-launcher" 
name="ubuntu-clock-app.ubuntucoredev_clock_3.6+snap2" pid=2080 
comm="ubuntu-core-lau" target="ubuntu-clock-app.ubuntucoredev_clock_3.6+snap2"

  Downgrading to ubuntu-core-launcher doesn't help the clock app get
  past this failure.

  The hello-world app works ok (it needs ubuntu-core-launcher 1.0.20 since it 
gets past the above error and the launcher needs to account for NO_NEW_PRIVS):
  $ hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  $ sudo /snaps/bin/hello-world.env |grep SNAP=
  SNAP=/snaps/hello-world.canonical/6.0

  cap-test.mvo doesn't have this problem either:
  $ sudo snappy install cap-test.mvo
  $ cap-test.xbomb

  If I disable the apparmor profile with: sudo apparmor_parser -R
  /etc/apparmor.d/usr.bin.ubuntu-core-launcher then the app will launch.

  Downgrading to the -13 kernel resolves the issue:
  $ cat /proc/version_signature

Bug description:
  The following patch has been submitted upstream in response to
  investigation of customer issues with network connections hanging
  under high load.

  On the consumer side, we have interrupt driven flow management of the
  producer. It is sufficient to base the signalling decision on the
  amount of space that is available to write after the read is complete.
  The current code samples the previous available space and uses this in
  making the signalling decision. This state can be stale and is
  unnecessary. Since the state can be stale, we end up not signalling
  the host (when we should) and this can result in a hang. Fix this
  problem by removing the unnecessary check.

  I would like to thank Arseney Romanenko 
  for pointing out this bug.

[Kernel-packages] [Bug 1528101] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From ru...@us.ibm.com 2016-03-28 16:01 EDT---
Minor changes to the kernel handling of user_min_free_kbytes appears to be the 
ideal solution here since it would have benefits outside of the kdump 
environment.  Currently, it appears that it is too easy to manually set a 
completely inappropriate value.  Elsewhere, the value is capped at either 65536 
or 5% of lowmem, but it appears that the user provided value is not run through 
the same sanity checks (see init_per_zone_wmark_min() as an example).

  Yes, I just found that if use the default min_free_kbytes value then
  kdump works just fine!

[Kernel-packages] [Bug 1562989] Re: 'aa_change_onexec failed with -1. errmsg: Permission denied'

I took the hello-world application, then adjusted its yaml to be the
same as the ubuntu-clock-app (using ubuntu-cl0ck-app as the name) and
was unable to reproduce.

Bug description:
  NOTE: kgunn suggests this bug be about 1) not 2) here

  1)
  I have been noticing my phone and tablet occasionally turning on without 
interaction. Several times with my phone in my pocket I found it in the 
emergency call UI
  I also see the tablet display turn on while lying idle on the desk. Freiza & 
Arale

  2)
  I have reproduced one case such that turning on a BT device (headset) causes 
the phone to light up and display the volume slider. Similarly turning on the 
BT keyboard while the tablet screen is off caused the display to turn on.These 
may be as intended.

  I suspect other BT events can similarly resume the device and/or turn on the 
display if it happens to be awake due to the 5 min polling timer.
  The proximity sensor is also not honored when this happens, if its covered 
the screen still comes on.

[Kernel-packages] [Bug 1562510] Re: Crash on Thinkpad T420s when battery goes low

[Rovanion]

It only started after the upgrade. The last kernel I ran which worked perfectly 
fine was kernel 
3.13.0-83-generic:i386.  The bug seems to not be present with the 4.5 kernel, 
though I've only done minor testing.

Bug description:
  After OTA-9 I started having trouble with my bluetooth connection to the car 
hands-free system (no sound, and incoming calls no longer displayed the 
number), so I have reset both the car and the phone connections (eg. forgot the 
devices).
  Now I can't even pair the phone with the car's system. 
  The car finds the phone, and then asks me to enter the code "" to pair 
the device, but after a few moments, it just says the connection failed and 
asks me to try again. Which fails again.

  It was working fine just before the update.

  Any logs I should post to help debug?

  PS - The car is a 2015 Honda Civic Tourer, if that matters.

[Kernel-packages] [Bug 1562618] Re: whole OS freezes seemingly randomly

[Vincent Gerris]

Hi,

I started having problems after the upgrade to 16.04 beta.
I think the last kernel before the update from 15.10 was 4.2.0-35. 
The mentioned bug report mentioned this being an issue with a graphics driver, 
I guess it is that.
The last freezes happened after playing video.

I installed the 4.5 kernel and I have been playing over an hour of video
without freeze (still no freeze at vt switching either).

So now I have:
vincent@vincent-Lenovo-Yoga-2-11:~$ uname -a
Linux vincent-Lenovo-Yoga-2-11 4.5.0-040500-generic #201603140130 SMP Mon Mar 
14 05:32:22 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Does this mean the 4.5 kernel will be included in the final 16.04 ?
added tag kernel-fixed-upstream.

Do I need to mark this a confirmed now?
I could test a little longer, but it seems ok.

Thank you.

Reinstalling Google Chrome seems to have solved the problem.

[Kernel-packages] [Bug 1549354] Re: After upgrading to 4.2.0.30 Elantech touchpad not detected

[Joseph Salisbury]

I built the next test kernel, up to the following commit:
3e8e33a682b8c83b6079684834b1d6654c541df5

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1549354

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.

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

[Joseph Salisbury]

I tested CentOS 7 with LIS 4.1 over the weekend, and it also did not
exhibit the bug.   This might indicate a regression introduced after the
v3.10 kernel, or maybe that CentOS 7 has a distro specific fix that is
not in Ubuntu yet.

I'll try some newer kernels on CentOS and some older kernels on Ubuntu
to try to narrow this down further.

  Customers have reported running various versions of Ubuntu 14.04.2 LTS

  will be mounted Read-Only due to a "disk error" (which really isn't
  the case here).As a result, they must reboot the Ubuntu guest to
  get the file system to mount RW again.

  The Error seen are the following:

  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.

  Broadcom bluetooth chips require a tool called patchram uploader [1]
  to load firmware. This applies to at least BCM20702 and BCM43142.
  Although some of the devices have an OTPROM that contains required
  firmware, but it is found that these devices would not have HFP/HSP
  support unless a upgraded firmware is loaded via patchram uploader.

  This tool requires hci device to do the firmware loading, but this may
  cause some race condition between patchram tool and bluetoothd or
  something that also works on hci interface.

  Also it needs some hooks to make firmware loads after bootup, s3,  s4,
  rfkill, and device hotplug events. Implement this loader in kernel
  module would make things more easier.

Hey!

I'm also facing this problem, I recorded a video about it:

https://www.youtube.com/watch?v=l21WsKz3fZc

I tried to move away from XOrg, by using GNOME+Wayland, but, problem
persist, Wayland is faster, however, I can still see it flickering
(faster).

Problem with GNOME+Wayland is that it completely freezes my Macbook.

  ThunderX: support alternative phy implementations

Status in linux package in Ubuntu:

Bug description:
  Different implementations of ThunderX use different underlying phys.
  The driver currently fakes a hard dependency on one of these phy
  drivers to make sure it gets loaded (mdio-octeon) - but changes have
  landed upstream to switch this over to deferred probing, so that
  devices can be discovered as the other possible phy drivers get
  initialized. These phy drivers also need to be made available at
  install time.

[Kernel-packages] [Bug 1543683] Re: Fails to detect (second) display

[LaMont Jones]

Said kernel appears to be good.  The reshuffling of windows does not
occur (and I get two displays!!)  In the worst case, I'd recommend
shipping xenial with 237ed86c reverted, if they can't get a fixed
version before our deadline.

Holler at me if there's another kernel for me to test.

thanks,
lamont

[Kernel-packages] [Bug 1562076] Re: Ubuntu freezes a few seconds after plugin a screen

[Axel "Black Eco" Leroy]

I do not know if an update brought this issue because I did not plugged any 
monitors since I updated from wily. 
I installed kernel 4.5 but the bug is still present. I wonder if the issue 
comes from Xorg instead of the kernel.

  Hello,

  I'm running the latest beta of Ubuntu 16.04 Xenial on an ASUS UX303LA (Intel 
i5 6200U, Intel HD 520) and each time I plug a screen, using either HDMI or 
Mini DisplayPort, my laptop freezes after a few seconds.
  Alt + Function keys doesn't work, sound stops and I'm forced to shutdown the 
computer by long-pressing its Power button.

  I attached syslog, kern.log and Xorg.0.log for further information.

[Joseph Salisbury]

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

If that does not resolve your issue, please mark the bug as "Confirmed"

[Kernel-packages] [Bug 1561943] Re: Stylus coordinates wrong when screen is rotated on Dell Venue 11 Pro 7140

[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
v4.5 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.

  Stylus coordinates wrong when screen is rotated on Dell Venue 11 Pro
  7140

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I am using the pre-release 16.04 Ubuntu Xenial Xerus (development
  branch) with kernel 4.4.0-15-generic on a Dell Venue 11 Pro 7140.
  Touchscreen and Stylus are recognised out of the box:

  xinput --list
  ⎡ Virtual core pointerid=2[master pointer  (3)]
  ⎜   ↳ Virtual core XTEST pointer  id=4[slave  pointer 
 (2)]
  ⎜   ↳ Synaptics T Pad V 01.31 Touchpadid=9[slave  pointer 
 (2)]
  ⎜   ↳ SYNA7500:00 06CB:780E Pen   id=13   [slave  pointer 
 (2)]
  ⎜   ↳ SYNA7500:00 06CB:780E   id=14   [slave  pointer 
 (2)]

  When I am manually rotating the screen by 90° using the System
  Settings option (automatic screen rotation does not work), the
  touchscreen and touchpad work as expected, however, the stylus is not
  using the correct coordinates and the cursor is not following the
  stylus position. When I move the stylus left/right, the cursor moves
  up/down, and vice versa.

  I had hoped to get a work around by disabling and re-enabling the
  stylus after rotating the screen using

  xinput --disable "SYNA7500:00 06CB:780E Pen"
  xinput --enable "SYNA7500:00 06CB:780E Pen"

  but this didn't solve the problem.

  I am not able to boot my  Power Mac 7,3 with the Ubuntu MATE 16.04

  This has been the case since the 4.3.x kernel series and is now with

  the iso went fine!**

  During the boot-process I get following error messages:

  The stdin: and mount: lines get repeated several 10 time. At last the
  boot process stops wuth the (initramfs) line, dropping me in a busybox

[Kernel-packages] [Bug 1534216] Re: lots of printk to serial console can hang system for long time

[Dan Streetman]

this is (mostly) fixed in 2 commits, from the original bug (bug 1505564)
kernel level commit 5a3a466ae3c86ad6b8fc36c2efc5f541ef0ed89e (from
git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git lts-backport-vivid)
partially fixes this problem, by using the console_may_schedule var
correctly.  The recent upstream commit
6b97a20d3a7909daa06625d4440c2c52d7bf08d7 (from upstream) completes
fixing the problem, by setting console_may_schedule correctly.

Title:
  lots of printk to serial console can hang system for long time

Status in linux package in Ubuntu:
  In Progress

Bug description:
  This is a clone from bug 1505564, to track the separate issue of the
  serial port driver failing to schedule itself off its cpu.

  The original bug's problem was caused by the kernel spamming a huge
  number of error messages in a certain situation.  Normally, that would
  not be a problem, but in this case the system is virtualized, and logs
  over its serial port.  When the massive number of kernel messages are
  sent to the serial port driver, it can't keep up, so sending all the
  log messages can take a very long time - minutes or longer - and the
  serial port driver fails to schedule itself off the cpu it's using
  during that time.  That results in other cpus hanging, waiting for the
  serial port driver's cpu to become avaiable.

  I'll  update the bug with more details as I debug.

Title:
  Hard disk writes fail in 16.04 daily on nForce 430

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I have an old PC I use for testing new operating systems.  It has
  previously had Ubuntu 15.10 installed and working.  The motherboard is
  an Asus M2NPV-VM, with Nvidia nForce 430 chipset and Nvidia GeForce
  6150 GPU.  I have installed an Nvidia GT220 card to use for more
  modern video support.

  When I attempt to install Ubuntu 16.04 beta (daily xenial-desktop-
  amd64.iso file downloaded 24/03/2016  18:17), it starts to write to
  the hard disk (Samsung HD103UJ), and after a short time the install
  got lots of disk write errors in kern.log.  After the errors, the disk
  was unable to be read either, with "fdisk -l /dev/sda" failing to read
  a sector, where it had worked before starting the install.  Unplugging
  the SATA cable to the drive and plugging it in again made the drive
  work again (on /dev/sdc), but another attempt to install failed with
  the same write errors.

  I noticed that the log had swap write errors also, so I rebooted the
  install DVD again, and this time did a "swapoff -a" command before
  attempting to install, but got the same errors again.  So I found my
  Ubuntu 15.10 install DVD and tried a new install from that, which
  worked just fine.

  On rebooting with my 16.04 daily DVD, I again did "swapoff -a" so that
  the DVD based system would run normally, then tried mounting the EXT4
  system partition I had just installed using the 15.10 install DVD.
  That worked, so I tried dd commands to do test writes to that
  partition.  The following commands worked:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=10k
dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=100k

  but when I did this command:

dd if=/dev/zero of=/mnt/sda8/tmp/output bs=8k count=1000k

  after a while errors started appearing in kern.log, just as with the
  attempts to install 16.04.

  It appears that with sustained write activity, the errors will start
  and then the drive will become unusable until it is unplugged and
  plugged in again.

  I have attached the kern.log and syslog files from the 15.10 install
  that worked, and the 16.04 install attempt that failed.  The first
  error message appears to be this:

  ata3: EH in SWNCQ mode,QC:qc_active 0x1FFF sactive 0x1FFF
  ata3: SWNCQ:qc_active 0x1 defer_bits 0x1FFE last_issue_tag 0x0
  dhfis 0x1 dmafis 0x0 sdbfis 0x0

  which leads me to suspect a problem with the handling of the SATA 
controller's interrupts.

[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
v4.5 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.

You may need to run the following from a terminal:

sudo apt-get install -f
sudo apt-get clean
sudo apt-get update

Then re-install the package or updates.

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