[Kernel-packages] [Bug 1510344] Re: Keyboard Backlight Turns on at boot

[Matthias König]

Addendum: I noticed the backlight also gets switched back on after not
using the keyboard and touchpad for a few seconds. I suspect this has
something to do with the way it acts when it is switched on normally:
After not typing anything or using the touchpad for a few seconds, the
backlight is switched off to save power and gets switched back on when
you touch the keyboard.

[Kernel-packages] [Bug 1488719] Re: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

[Puggan]

Got this error in my dmesg, and gets daily KDM crashes.

Have an Asus X555L with 2 external monitors connected,
each morning when i get back to the computer, the laptop screen dosn't start,
and I have no working window managment => I can use the active window, but 
can't change active window.

Also, if i activate the wireless-card, I can see the si (software interupt) in 
top raise to 100%, and then I lose all controll.
And all I found so far is this error message 1836 times in the dmesg-log

  This may require the ACPI backlight driver to not take control so that
  a vendor specific driver will have a chance to register.

  I wanto mention that this goes beyond just the applet not working.  My
  data does change in Ubuntu for those entries and the acpi interface to
  the Linux Kernel is not able to use that changed data to change the
  hardware brightness setting.

  There are multiple problems with tape drives when using a media changer on an

  The problem appears for example when you label tapes in Dell Netvault.

  The problem does not appear in current vanilla kernel 4.2.3.

  [SCSI] hpsa: allow SCSI mid layer to handle unit attention

  We were clobbering the SCSI status and setting
  cmd->result = DID_SOFT_ERROR << 16; to get a retry,
  but better to let the mid layer handle the unit
  attention.

  thanks to git bisecting rules:
  good = label errors = old kernel
  bad = no label errors = newer kernel

  Please consider backporting that fix to the 3.13 ubuntu kernel.

I created a new LVM Volume and a new ext3 FS. I copied the whole FS from
ext4 to ext3 and running now the VM on ext3.

Today the ext4_mb_generate_buddy bug did hit me agian. With ext3 FS and
running the VM with "cache=none" setting.

Bug description:
  update: updated the BIOS to the latest version but the problem
  persists.

  Booting with the older kernel (latest linux kernel from 12.10) every thing 
works fine. After upgrading to Raring Ringtail Ubuntu 13.04, with the new 
kernel, hardware get blocked/disabled and wireless doesn't work:
  0: phy0: Wireless LAN
   Soft blocked: no
   Hard blocked: yes
  1: asus-wlan: Wireless LAN
   Soft blocked: no
   Hard blocked: no

  WORKAROUND - is only applicable to Asus Notebooks/netbooks that use the 
"asus_nb_wmi" driver:
  Create and edit asus_nb_wmi.conf file with this command:
  sudo echo "options asus_nb_wmi wapf=4" | sudo tee 
/etc/modprobe.d/asus_nb_wmi.conf

  Ubuntu 14.04.03 LPAR hits kernel oops after serial adapter is removed
  from profile

Status in linux package in Ubuntu:

Bug description:
  -- Problem Description --

  The failure related to the BELL-3 (2 port-Async EIA-232 adapter).
  Ubuntu always hit exception when the adapter is not present. See my
  test scenarios below.

  Test #1: Boot Ubuntu with BELL-3 adapter 
  ===

  - The Ubuntu LPAR was running with the BELL-3 (2 port-Async EIA-232 adapter) 
before. So I assigned the BELL-3 adapter to Ubuntu LPAR profile and powered on 
the LPAR. 
  => Ubuntu boot fine this time.

   
  Test #2: Boot Ubuntu with BELL-3 adapter removed from LPAR profile
  ===

  - I powered down the Ubuntu partition and removed the BELL-3 adapter from 
LPAR profile then powered on the LPAR.
  => Ubuntu hit the exception.

[Kernel-packages] [Bug 1115555] [NEW] Backlight control does not work, but there are entries in /sys/class/backlight.

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Backlight control does not work, but there are entries in
/sys/class/backlight.

This may require the ACPI backlight driver to not take control so that a
vendor specific driver will have a chance to register.

I wanto mention that this goes beyond just the applet not working.  My
data does change in Ubuntu for those entries and the acpi interface to
the Linux Kernel is not able to use that changed data to change the
hardware brightness setting.

[Kernel-packages] [Bug 1384342] Re: kernel messages intel_crtc_wait_for_pending_flips correlate to compiz hang

[Mike]

Upgrading to 3.16 still caused display to crash.

I've successfully upgraded to kernel 3.19 (3.19.0-31-generic) and
haven't experienced the display crash issue since.

 sudo apt-get install linux-generic-lts-vivid

I only ran into one issue with the i915 DKMS module crashing and fixed it by 
installing the 3.19 version:
  
 sudo apt-get install i915-3.19-3.13-dkms

Since those two package upgrades, my 14.04.3 LTS install has been
running great.

Bug description:
  I am fairly frequently (maybe once every 2 days) seeing screen
  lockups.  The system is fine, and then screen locks up. mouse is still
  movable and even changes icon based on content under it (ie mouse over
  link changes to pointing hand).  Programs are still running (often
  this occurs during a google hangout, and the hangout, audio and mic
  seem to work fine).

  Today when this happened I had more patience and hit ctrl-alt-f1, and then 
subsequently saw that dmesg had:

Contrary to bug #111, nothing changes after changing the brightness
in MacOSX and rebooting back into Ubuntu. I'm still at maximum
brightness.

Bug description:
  Backlight control does not work, but there are entries in
  /sys/class/backlight.

  This may require the ACPI backlight driver to not take control so that
  a vendor specific driver will have a chance to register.

  I wanto mention that this goes beyond just the applet not working.  My
  data does change in Ubuntu for those entries and the acpi interface to
  the Linux Kernel is not able to use that changed data to change the
  hardware brightness setting.

[Kernel-packages] [Bug 1505242] Re: WARNING: ... intel_display.c:11100 intel_check_page_flip

Visi Bilius, could you please test the latest mainline kernel (4.3, not
4.3-rcX) and advise to the results?

Bug description:
  I see warnings similar to this occasionally in the dmesg output.
  I first noticed it, when the system refused to put load on all but one core, 
and I tried to find the reason.
  But it happened again a few times, and I did not notice that effect (or any).
  I do not know the trigger. I suspect playing video.
  This is a fresh install of Ubuntu 15.04 on a fresh hardware.

  I found several similar error reports with google. All appeared to be 
unsolved.
  I thought, I submit this report, anyway. Perhaps it provides some new 
information.

[Kernel-packages] [Bug 123920] Re: Bluetooth Logitech Dinovo Keyboard/Mouse don't work

[Daniel Beauyat]

The solution from Dhanish Patel solved my problem with Logitech Cordless MX 
5500 on Ubuntu 15.10 Wily Werewolf!
I have keyboard/mouse combo from Logitech named Logitech Cordless MX 
(Revolution) 5500; this combo has 1 bluetooth dongle to receive input from both 
mouse and keyboard.

I was using it without problem on Ubuntu 14.04 LTS.
I just switched to Ubuntu 15.10 and keyboard/mouse do not work at all!!! After 
some search, I found this webpage and tried that solution:
Change: KERNEL=="hiddev*"
To: KERNEL=="hidraw*"
After reboot, MX 5500 Wireless keyb/mouse combo now works on Wily Werewolf.

On 15.10 Wily Werewolf though, the path to the modified file is:
/lib/udev/rules.d/97-hid2hci.rules

I modified line 14:
From: KERNEL=="hiddev*", ATTRS{idVendor}=="046d", 
ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \
To: KERNEL=="hidraw*", ATTRS{idVendor}=="046d", 
ATTRS{idProduct}=="c70[345abce]|c71[3bc]", \

Thanks for sharing the solution :)

[Kernel-packages] [Bug 1512406] Re: Green Screen instead of video stream

[Joseph Salisbury]

This issue appears to be an upstream bug, since you tested the latest
upstream kernel. Would it be possible for you to open an upstream bug
report[0]? That will allow the upstream Developers to examine the issue,
and may provide a quicker resolution to the bug.

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

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

Still happens on 4.3 mainline.  It's happened on every kernel I've used

Bug description:
  Occasionally the screen will blank and all windows move from the
  external monitor to the laptop monitor.  Relatively immediately
  afterward both screens re-enable, but the windows don't move back to
  the external monitor.

  This usually appears to be triggered by a specific application, eg,
  "ScudCloud" (a slack client that embeds an HTML webkit view), or
  enabling the flash plugin in an existing firefox window.

[Kernel-packages] [Bug 1492146] Re: igb Detected Tx Unit Hang

[Joseph Salisbury]

The commits that caused this bug were introduced by the fixes for bug
1454892.

I've created a new test kernel for bug 1454892, but I would like to
ensure it does not introduce this regression again.  Could folks
affected by this bug test my new test kernel?  It can be downloaded
from:

http://kernel.ubuntu.com/~jsalisbury/lp1454892/lts-backport-utopic/

Note, with this test kernel you would need to install both the linux-
image and linux-image-extra .deb packages.

Thanks in advance!

  read() from pty doesn't finish.

Status in linux package in Ubuntu:
  In Progress

Bug description:
  It has been brought to my attention

  By the attached test program pty, a pair of process repeats writing
  and reading only '\n' to a master pseudoterminal device (/dev/ptmx)
  and a slave pseudoterminal device (/dev/pts/N) each. When we carry out
  the following 30 pairs 10,000 times, in a pair each process doesn't
  finish reading.

  $ pty 30
  The following message will be usually indicated immediately.
  #name copy num/sec usec/num
  pty_switch 30 1541842 0.648575

  When a message wasn't indicated any more, we got the attached dump file. 
  A kernel was 3.13.0-45.74. 
  A system was Ubuntu 14.04 LTS.

  The same problem occurred in case of 3.13.0-55.92 kernel and the following 
kernel have been tested as well:
  2.6.32, 3.10: not reproduces.
  3.19, 4.0.0, 4.1.3: reproduces.

[Kernel-packages] [Bug 1512815] Re: 14.04: read() from pty doesn't finish.

[Eric Desrochers]

This is a reproducer for the stall problem in drivers/tty/n_tty.c

To reproduce the problem, save the program below as pty.c, compile it,
and run it in parallel.

# cc -o pty pty.c
# for i in {1..16}; do ./pty& done; wait
The problem can be reproduced on a multi-socket server with recent CPUs.
The program always stalled during the first run when I used a server
with the following CPU.
  Intel(R) Xeon(R) CPU E5-2698 v3 @ 2.30GHz
  2-sockets x 16-cores x 2-threads

[Kernel-packages] [Bug 1512815] Re: 14.04: read() from pty doesn't finish.

[Eric Desrochers]

According to the dump a pair of process PID 7347 and 7348 were still
waiting for read() from /dev/ptmx (struct file 880c65357c00) and
/dev/pts/18 (struct file 880c65357500) respectively .

Normal behavior is as follows;
PID 7347: read(/dev/ptmx) -> write(/dev/ptmx),
PID 7348: write(/dev/pts/18) -> read(/dev/pts/18).

In the dump, PID 7348 finished writing to /dev/pts/18, and was waiting
for completion of reading, while PID 7347 continued waiting for reading
/dev/ptmx.

Though data has already arrived at /dev/ptmx, PID 7347 doesn't seem to
have been woken up while being linked to the queue of the data to be
read at tty_struct 0x88085438ac00.

[Kernel-packages] [Bug 1512848] [NEW] Radeon VCE Init Error

Public bug reported:

Since upgrading to Ubuntu 15.10, I have encountered graphics performance
issues, and have occasionally experienced lockups during boot.

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.3 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as
"Confirmed".


Thanks in advance.

[Kernel-packages] [Bug 1509029] Re: [Hyper-V] Crash in hot-add/remove scsi devices (smp)

[Joseph Salisbury]

Thanks for the test results, Chris.  I also built Trusty and Vivid test 
kernels.  The can be downloaded from:
Trusty: http://kernel.ubuntu.com/~jsalisbury/lp1509029/trusty
Vivid:  ttp://kernel.ubuntu.com/~jsalisbury/lp1509029/vivid

Can you give these kernels a test as well.  I'll submit an SRU request
for them as well if the testing is good.

Thanks again.

Bug description:
  On some host errors storvsc module tries to remove sdev by scheduling a job
  which does the following:

 sdev = scsi_device_lookup(wrk->host, 0, 0, wrk->lun);
 if (sdev) {
 scsi_remove_device(sdev);
 scsi_device_put(sdev);
 }

  While this code seems correct the following crash is observed:

   general protection fault:  [#1] SMP DEBUG_PAGEALLOC
   RIP: 0010:[]  [] bdi_destroy+0x39/0x220
   ...
   [] ? _raw_spin_unlock_irq+0x2c/0x40
   [] blk_cleanup_queue+0x17b/0x270
   [] __scsi_remove_device+0x54/0xd0 [scsi_mod]

   [] storvsc_remove_lun+0x3d/0x60 [hv_storvsc]
   [] process_one_work+0x1b1/0x530
   ...

  The problem comes with the fact that many such jobs (for the same device)
  are being scheduled simultaneously. While scsi_remove_device() uses
  shost->scan_mutex and scsi_device_lookup() will fail for a device in
  SDEV_DEL state there is no protection against someone who did
  scsi_device_lookup() before we actually entered __scsi_remove_device(). So
  the whole scenario looks like that: two callers do simultaneous (or
  preemption happens) calls to scsi_device_lookup() ant these calls succeed
  for all of them, after that both callers try doing scsi_remove_device().
  shost->scan_mutex only serializes their calls to __scsi_remove_device()
  and we end up doing the cleanup path twice.

[Kernel-packages] [Bug 1512769] Re: Touchpad not working

[Gregor Eesmaa]

1. I think I've successfully used the touchpad on this device with Ubuntu 14.10 
in the past even though it wasn't recognized as a touchpad and I couldn't use 
multi-finger gestures with it - perhaps an attempt to fix it could've resulted 
in it not working in this version of Ubuntu? 
2. The specified kernel (v4.3-unstable or v4.3-wily) didn't fix the problem.

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

[ubuntu]

Sorry for the long delay in posting results but I did want to share what we've 
learned.
1) The failures happen during the VSS Snapshot/checkpoint creation process.   
You can reproduce the errors by doing manual VSS snapshots.
2) The heavier the VM load, especially I/O,  the more likely the error will 
occur.
3) Every kernel posted (including the Willy) share the same problem - 
differences were not significant between them.
4) During snapshot creation, even RHEL hits a bump. There's a small delay in 
response times but nothing that causes errors.  Installing LIS 4.0 doesn't make 
a difference.

Unfortunately, I can't follow-up with further testing.  After figuring
this out we cancelled the migration to Hyper-V and invested further in
our VMware infrastructure.   :(Thanks!

  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.

[Kernel-packages] [Bug 1509120] Re: Process accounting deadlock with idmapd callout when writing to NFSv4 mount

[Dave Chiluk]

Yeah, I think so, if you are "creative" enough to put your accounting on
your nfs mount, and then have your nfs service fail, you should expect
your machine to stop functioning.  Otherwise it could be a potential
accounting/security hole.

  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  ---uname output---

  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

  Problem Description
  ==
  I attempted to inject a Core Unit Checkstop error by flipping Core FIR bit 5 
on a K80 (Nvidia) 42L Server ( FSP - gp4fp1.aus.stglabs.ibm.com ). I was 
expecting the server to crash due to a Sapphire assert ( PEL with SRC BB821410 
) and a Sapphire dump to be collected in the process.

  However on injecting the error , the host ( Ubuntu NV ) crashed, and
  never recovered. OPAL however seemed to stay up and there were a
  plethora of mail box errors - B182953C logged by the FSP.

[Kernel-packages] [Bug 1512884] [NEW] hv driver in -lbm package not used

[Luis Henriques]

Public bug reported:

The driver in the linux-backports-modules-3.2.0 package is not being
used and is currently unmaintained.  It should be disabled, as the in-
kernel version seems to be preferred.

  Problem Description
  ==
  I attempted to inject a Core Unit Checkstop error by flipping Core FIR bit 5 
on a K80 (Nvidia) 42L Server ( FSP - gp4fp1.aus.stglabs.ibm.com ). I was 
expecting the server to crash due to a Sapphire assert ( PEL with SRC BB821410 
) and a Sapphire dump to be collected in the process.

  However on injecting the error , the host ( Ubuntu NV ) crashed, and
  never recovered. OPAL however seemed to stay up and there were a
  plethora of mail box errors - B182953C logged by the FSP.

[Kernel-packages] [Bug 1511511] Re: USB keyboard stops working after pressing extended key

[Daniel M. Lambea]

The keyboard was bought a few months ago and the bug have always been
there. I've tried the keyboard both in upgraded systems and in fresh
installations to no avail.

Following your instructions, I have just tested it right now using the
mainline kernel (at the URL you provided) and the bug is still showing,
so I proceed with adding the tag 'kernel-bug-exists-upstream'.

[Kernel-packages] [Bug 1484159] Re: Qualcomm Atheros Device [168c:0042] (rev 30) not working on Ubuntu

[Sasha]

Hay guys,

look at this

http://askubuntu.com/questions/678145/my-wifi-qualcomm-atheros-device-
168c0041-rev-20-doesnt-show-up-and-work-in

Seems like it's the second last version of this hardware we're talking about 
([168c:0041] (rev 20)).
I don't know if that is of any help, but I wanted to share it with you.

My thought is "is it that unlikely to say take this version and grade it
up to the newer version?". I'm not familiar with developing/programing
those things. And also a new linux user. I'm using the same machine and
have the same issue.

Best regards

[Kernel-packages] [Bug 1509776] Re: xubuntu 15.10 synaptics ps2 touchpad mouse cursor jumps

[liontamer]

Sorry I am being slow to think.  I tried installing kernel 4.30 in 15.04
in place of 3-3.19-0-31 and the bug is not present with either but it is
present in 15.10 with either 4.30 or 4.2.0-16.  This suggests to me that
the problem is not in the kernel.  I wonder if it is connected with
window snapping (although I have this turned off), not moving the window
but moving the cursor in anticipation?

Bug description:
  There are multiple problems with tape drives when using a media changer on an 
hpsa controller.
  The problem appears for example when you label tapes in Dell Netvault.

  The problem does not appear in current vanilla kernel 4.2.3.

  After bisecting the problem the actually first good commit is: 
  3ce438df106826edde7ad724f3819716a3f0cf56 is the first bad commit

  [SCSI] hpsa: allow SCSI mid layer to handle unit attention

  We were clobbering the SCSI status and setting
  cmd->result = DID_SOFT_ERROR << 16; to get a retry,
  but better to let the mid layer handle the unit
  attention.

  thanks to git bisecting rules:
  good = label errors = old kernel
  bad = no label errors = newer kernel

  Please consider backporting that fix to the 3.13 ubuntu kernel.

  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

  from customer:

   am uploading a crash dump file from a lock up event that I just had.
  I was reminded on a status update call this morning that I never tried
  running process accounting since opening the ticket and updating the
  kernel. So, I tried that this morning. The first time I turned it on
  with the default output location and didn?t have any problems. Then I
  tried turning it on with the output going to our shared disk space,
  which is where I was originally sending it. I ran a couple commands
  that returned just fine, then when I ran a CUDA test program it didn?t

[Dave Chiluk]

I verified that keyutils is already included in vivid+ in order to fix
1449074.  So this shouldn't be too much of an issue to fix in trusty as
well.

  mail server can work.

  It's a critical bug for me, can anybody help me?

[Kernel-packages] [Bug 1492146] Re: igb Detected Tx Unit Hang

[Mark Sapiro]

I have installed

linux-image-3.16.0-52-generic_3.16.0-52.71~14.04.1_amd64.deb and
linux-image-extra-3.16.0-52-generic_3.16.0-52.71~14.04.1_amd64.deb

from http://kernel.ubuntu.com/~jsalisbury/lp1454892/lts-backport-utopic/
and rebooted and I do not see the issue reported in this bug. It appears
at least for me that the above kernel does not have the regression.

[Kernel-packages] [Bug 1509120] Comment bridged from LTC Bugzilla

[bugproxy]

--- Comment From ru...@us.ibm.com 2015-11-03 20:56 EDT---
Thanks for chasing down the missing dependency side of the equation here.

That still leaves the potential of deadlock if the callout exec ever
returns non-zero for any other reason.  Are the risks considered low
enough to simply document this as a potential hazard of writing process
accounting information across an NFSv4 mount?

  Original Description

  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.

  ---uname output---
  Linux ppc001 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:21:52
  UTC 2015 ppc64le ppc64le ppc64le GNU/Linux

  ---Problem Details---

  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the
  trigger was turning on process accounting and writing to a file hosted
  via an NFSv4 mount.  During the testing, several vmcores were
  captured, and the fingerprint indicates a mutex deadlock situation
  with process accounting.   In the most recent vmcore, it appears that
  the scenario is something like the following:

  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

  PID: 4898   TASK: c01fd26d7580  CPU: 7   COMMAND: "ls"

[Kernel-packages] [Bug 1512815] Re: read() from pty doesn't finish.

[Joseph Salisbury]

I built a Wily test kernel with a cherry pick of commit e81107d.  The test 
kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1512815/

Can you test this kernel and see if it resolves this bug?

Note, you need to install both the linux-image and linux-image-extra
.deb packages.

Title:
  read() from pty doesn't finish.

Status in linux package in Ubuntu:
  In Progress

Bug description:
  It has been brought to my attention

  By the attached test program pty, a pair of process repeats writing
  and reading only '\n' to a master pseudoterminal device (/dev/ptmx)
  and a slave pseudoterminal device (/dev/pts/N) each. When we carry out
  the following 30 pairs 10,000 times, in a pair each process doesn't
  finish reading.

  $ pty 30
  The following message will be usually indicated immediately.
  #name copy num/sec usec/num
  pty_switch 30 1541842 0.648575

  When a message wasn't indicated any more, we got the attached dump file. 
  A kernel was 3.13.0-45.74. 
  A system was Ubuntu 14.04 LTS.

  The same problem occurred in case of 3.13.0-55.92 kernel and the following 
kernel have been tested as well:
  2.6.32, 3.10: not reproduces.
  3.19, 4.0.0, 4.1.3: reproduces.

  ---Problem Description---
  System hang when process accounting to a NFSv4 mount.
  
  ---uname output---
  Linux ppc001 3.19.0-30-generic #34~14.04.1-Ubuntu SMP Fri Oct 2 22:21:52

  ---Problem Details---
  
  We have a customer that is experiencing intermittent system hangs on
  their system.  After a bit of debug, it was discovered that the trigger
  was turning on process accounting and writing to a file hosted via an
  NFSv4 mount.  During the testing, several vmcores were captured, and the
  fingerprint indicates a mutex deadlock situation with process
  accounting.   In the most recent vmcore, it appears that the scenario is
  something like the following:
  
  1. PID: 4898 COMMAND: "ls" triggers a write to the process accounting file.
  2. The resulting NFS write needs idmapd information and calls out to idmapd
  3. The idmapd usermodehelper process triggers another process accounting 
update that blocks on the mutex being held by PID 4898.

[Kernel-packages] [Bug 1495043] Re: Suspend/Resume Regression 3.19.0-28-generic Dell xps15

[Joachim Van der Auwera]

I seem to have the same problem on a Dell M3800.
Unfortunately, I have no "wl" module installed, so that does not make a 
difference.
The problem appeared in a 15.04 in one of the last weeks before 15.10 release. 
It is still there in 15.10.

  To reproduce the bug:
  1) Boot into Ubuntu Gnome with kernel 3.19.0.28-generic
  2) Log in to desktop.
  3) Close laptop lid
  4) Wait about 10 seconds (doesn't seem to be critical how long you wait)
  5) Open laptop lid.

  What happens:
  The keyboard backlight and the power button light come on, but the screen 
remains blank.  Using Ctr-Alt-F1 does nothing (can't get to a virtual console, 
indicating that it's not just X that has stopped)

  What I expect to happen:
  On opening of the laptop lid, I expect the lockscreen to show.

  Other info:
  This laptop has nvidia graphics disabled using nvidia-prime

[Kernel-packages] [Bug 1512593] Re: :Ubuntu NV: Panic timeout=0 means Ubuntu does not reboot and recover from HMI (e.g. Core Unit Checkstop)

[Chris J Arges]

This is not a bug with our kernel config. Perhaps changing the userspace tool 
to check for this behavior and setting the sysctl value to the desired value 
may be possible.
Marking as Invalid for now, please feel free to reopen if you feel this is 
still an issue.
Thanks!

  Problem Description
  ==
  I attempted to inject a Core Unit Checkstop error by flipping Core FIR bit 5 
on a K80 (Nvidia) 42L Server ( FSP - gp4fp1.aus.stglabs.ibm.com ). I was 
expecting the server to crash due to a Sapphire assert ( PEL with SRC BB821410 
) and a Sapphire dump to be collected in the process.

  However on injecting the error , the host ( Ubuntu NV ) crashed, and
  never recovered. OPAL however seemed to stay up and there were a
  plethora of mail box errors - B182953C logged by the FSP.

Bug description:
  We have a rebuild test which is intended to confirm the kernel still
  builds when core-utils, gcc, ld etc change.  It makes no sense for
  this test to run for the kernel itself as it takes a very long time to
  run and we have literally just built the kernel with those tools.

  Check for the trigger being something other than the kernel packages
  themselves before doing the rebuild.

[Kernel-packages] [Bug 1488719] Re: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"

[Jeroko]

I get this error on my new Toshiba P50t-C-104, with kernel 4.3. No
monitors attached, just the default laptop screen. I get a black screen
after this message on boot. The only way to boot is to use the
'nomodeset' kernel parameter, but that dissables the intel graphics
card.

[Kernel-packages] [Bug 1129865] Re: [Broadcom Combo BT/Wifi Card] 21D3 21D7 Bluetooth does not detect anything at all

[Vincent Gerris]

also for 15.04 with 105b:e065 Product=BCM43142A0.
details for fix:
https://github.com/gnebehay/gnebehay.com/blob/master/contents/blog/lenovo-flexpad-bluetooth-debian/index.md
it works for 3.19. the 0-31-generic 4 bit kernel, I just had to :
sudo rfkill unblock all
to get the bluetooth soft unblocked before the un- and reload of the module.
I suppose that approach works for more hardware.

How can we get it in the kernel?

[Kernel-packages] [Bug 1065400] Re: Support for loading Broadcom bluetooth firmware

[Vincent Gerris]

patch for 105b:e065 : 
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1129865/comments/17 seems 
to be still absent.
Fix for it is in the link.
I asked Jesse what happened direction upstream.
Let's hope it gets in there

Bug description:
  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.

  Sometimes Ubuntu will freeze for a few seconds when you plug something
  into a USB 3.0 port; when Ubuntu comes out of the freeze, the device
  is still NOT recognised.

  No problems with USB 2.0 ports and devices.

  The USB 3.0 on this computer only works in Windows 7 (I'm dual booting
  Ubuntu 13.10 and Windows 7, both are 64-bit).

  Mounting upper over lower on mounting mount point works just fine:

  However if the directory name is misspelled (that is, we're providing
  wrong directory), the error message is misleading:

  32 root@MIKE /tmp/ofs> mount -t overlayfs myoverlay -o 
lowerdir=IAMWRONG,upperdir=upper mounting/
  mount: special device myoverlay does not exist

  
  I'm running this on Ubuntu 14.04.3 LTS, using 3.13.0-61-generic kernel.

  I'm not sure if this fits under 'linux' package, but I can't seem to be able 
to find 'mount' package in Launchpad.

  Subject: Re: Minutes from the Ubuntu Kernel Team meeting, 2015-03-24  
 

 
  I must confess I had hoped ubuntu would adopt fq_codel as the default 
 
  qdisc in this go-around. It is still not quite part of fedora´s   
 
  default either, but is now in arch, (and nearly everyone else 
 
  downstream from systemd), and has long been the default in openwrt,   
 
  and at this point, just requires a single sysctl to enable.   
 

 
  It certainly could use more widespread testing, perhaps in the next release?  
 

 
  d@nuc-client:~$ cat /etc/sysctl.d/10-bufferbloat.conf 
 
  net.core.default_qdisc=fq_codel

  rm -r * fails to delete directories when using overlayfs in a user-
  namespace.

  If overlayfs is mounted as follows,

     mount -n -t overlay overlay -o
  lowerdir=lowerdir,upperdir=upperdir,workdir=workdir mntpt

  and if lowerdir contains lowerdir/foo/bar.txt, then,

     rm -r mntpt/foo

  fails with error message,

     "rm: cannot remove ‘mntpt/foo’: Operation not permitted"

  strace shows,

  unlinkat(AT_FDCWD, "mntpt/foo", AT_REMOVEDIR) = -1 EPERM
  (Operation not permitted)

  OS details: 64-bit ubuntu 14.04.2 with the linux-generic-lts-vivid
  kernel (3.19).

  The bug does not occur on ubuntu 14.04.2 with the default linux-
  generic 3.13 kernel.

  The bug occurs for any vanilla 3.18+ kernel to which the 1-line patch,
  "overlayfs: allow unprivileged mounts" is added.  (The patch is at,
  http://kernel.ubuntu.com/git/ubuntu/ubuntu-
  vivid.git/commit/?id=78ec45495b15d27d4cc6d05cc454e30ec5b587ea)

  The bug occurs regardless of whether the filesystem underlying
  overlayfs is tmpfs or ext4.

  The bug also occurs when running ubuntu 15.04 (ubuntu vivid) in a
  virtual machine (qemu-system-x86_64).  The host is ubuntu 14.04.2 with
  the default 3.13 kernel.

  A script which reproduces the bug is attached and is also available at
  http://paste.ubuntu.com/11974137/

  - Executed LXC command: lxc-clone -s -B overlayfs orig test (both 
unprivileged containers)
  - LXC version: 1.0.7

  We discussed this on the LXC user mailing list, and this is likely a bug in 
one of the patches that add support for unprivileged use of overlayfs.
