["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Daniel Arnitz, could you please test the latest upstream kernel available (3.15-rc7) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-3.15-rc7

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [Lenovo ThinkCentre M91p] System freezes

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  * Problem description: The system freezes completely. This includes
  screen, mouse, and keyboard including numlock light. Even after
  several weeks of testing I was not able to tie the freezes to a
  specific event, program, or behavior. There seem to be a few scenarios
  where freezes are more likely (see below), but they can essentially
  occur at any time. I have updated my bios and the system; this did not
  solve the problem. I have not yet tried the mainline kernel, since I
  am unsure which version to select.

  * Steps to reproduce: Run long-term measurement device remote control in Matlab (data collection; SCPI, low cpu load, some network, a couple GB RAM usage). The system typically freezes within 24 to 48 hours. I have also tried several other scenarios:
  - normal work with KDE (Kile, Thunderbird, Firefox, Inkscape, VLC, Dolphin): RARELY (~ once a month)
  - measurement device remote control in Matlab (memory, network).

  The following didn't seem to reproduce the problem:
  - running date + sleep in a bash loop.
  - running date + sleep in a bash loop within screen.
  - running ping constantly.
  - idle loop in Matlab (do nothing).
  - random data copying loop in Matlab (memory only).

  * Keeping CPU load high by inverting a some matrix in the data
  collection loop seems to prevent this problem.

  * Last working version: Kubuntu 11.10

  * Additional information:
  - memory test came back negative (no problems)
  - crash is reproducible on a text console
  - could not obtain trace dump (system does not react to keyboard)

  Neither of the following fixed the problem:
  xserver-xorg-lts-quantal libgl1-mesa-dri-lts-quantal:i386 libgl1-mesa-glx-lts-quantal:i386

  or fixing the "*BAD*gran_size" issue described in:
