Title:
  desktop freeze, htop shows kernel thread at 100% cpu

Status in linux package in Ubuntu:
  Expired

Bug description:
  Every few hours the desktop freezes.  I can still login via ssh, htop
  shows one process running at 100%.  The process is shown in red,
  indicating a kernel thread.   No response to ctrl-alt-f1  or to
  service lightdm restart.

  Graphics card is NVIDIA NVS 310.

  I've tried the NVIDIA drivers in various versions up to nvidia-
  current, and also nouveau (current bug report is with logfiles etc
  generated after a crash while running nouveau).

  Xorg.log shows a seg fault:

Well, I am not a strong graphical software user. Most of the time I am
using gvim to edit program files. One of the times I had the problem I
captured dmesg. Below you will see what I got (through ssh, I guess).

It would be nice to get a /var/log/Xorg.log capture, just to show that
it is really the same thing.

Title:
  desktop freeze, htop shows kernel thread at 100% cpu

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Every few hours the desktop freezes.  I can still login via ssh, htop
  shows one process running at 100%.  The process is shown in red,
  indicating a kernel thread.   No response to ctrl-alt-f1  or to
  service lightdm restart.

  Graphics card is NVIDIA NVS 310.

  I've tried the NVIDIA drivers in various versions up to nvidia-
  current, and also nouveau (current bug report is with logfiles etc
  generated after a crash while running nouveau).

[Kernel-packages] [Bug 1526657] Re: desktop freeze, htop shows kernel thread at 100% cpu

2016-01-17 Thread tojb
>>So, my conclusion is that the problem happens exactly when the screen
saver takes control and the monitor turns off.

For me it was any sporadically associated with any graphics-related
operation, eg zooming in google earth, or opening a 3D molecule viewer.
I have swapped out the NVS 310 graphics card for an older FX 1800 and
had only one crash of this type since then, instead of the many per day
that I was getting before.

[Kernel-packages] [Bug 1526657] Re: desktop freeze, htop shows kernel thread at 100% cpu

2016-01-17 Thread Alberto Sentieri
I have exactly the same problem in both an Ubuntu 14.04 that I use at
work and a Debian Jessie that I use at home, and the software is up to
date. Both systems have a "VGA compatible controller: NVIDIA Corporation
GF119 [NVS 310] (rev a1)" and two monitors. After the problem shows up,
I can login into my system through ssh, but the console is dead.

The problem never happens when I am using the system, only when the
screen saver takes control and monitors turn off. I am not familiar with
the guts of the screen saver and why the monitors turns off: one
possibility is the video signal going away during the screen save
operation; another is the computer explicitly asking the monitor to turn
off. Anyway, the fact is that the monitor turns off and that may cause
the problem.

I found a work around at work which virtually made the problem go away:
I have the option (on the special monitors I use at work) to never  turn
them off, even when there is no video signal coming from the computer.
When I activate this monitor feature, the problem goes away. At home,
however, my monitors do not have this feature and I have the dead
console problem every few days. At work, in the last 6 months (and after
never turning my monitors off) I have had the dead console problem just
once, and that could be a different problem.

So, my conclusion is that the problem happens exactly when the screen
saver takes control and the monitor turns off. Hope that help you guys
solve the problem. My current Debian kernel version is “Linux version
3.16.0-4-amd64 (debian-ker...@lists.debian.org) (gcc version 4.8.4
(Debian 4.8.4-1) ) #1 SMP Debian 3.16.7-ckt20-1+deb8u2 (2016-01-02)”

Title:
  desktop freeze, htop shows kernel thread at 100% cpu

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Every few hours the desktop freezes.  I can still login via ssh, htop
  shows one process running at 100%.  The process is shown in red,
  indicating a kernel thread.   No response to ctrl-alt-f1  or to
  service lightdm restart.

  Graphics card is NVIDIA NVS 310.

  I've tried the NVIDIA drivers in various versions up to nvidia-
  current, and also nouveau (current bug report is with logfiles etc
  generated after a crash while running nouveau).

  Xorg.log shows a seg fault:

[Kernel-packages] [Bug 1526657] Re: desktop freeze, htop shows kernel thread at 100% cpu

2015-12-16 Thread 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
v4.4 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.
