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

Remco, could you please confirm this issue exists with the latest
development release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains,
could you please run the following command in the development release
from a Terminal (Applications->Accessories->Terminal), as it will
automatically gather and attach updated debug information to this
report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. 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-v3.11-rc4

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

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

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:
  [Clevo M570RU] CPU stalls occur when not using mouse or keyboard

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I noticed the problem when playing videos or music. When I don't
  constantly use the mouse or keyboard (such as continuously tapping on
  the Up key) the movie stops playing and the music starts repeating the
  same buffer (the characteristic computer hang sound). When I touch the
  mouse or keyboard again, the computer continues. In kern.log I found
  the following line:

  INFO: rcu_sched detected stalls on CPUs/tasks: { 1} (detected by 0,
  t=15603 jiffies)

  So I thought it might have something to do with that.
