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

Matthieu Baerts, it would not be necessary to file a new report at this
time.

Could you please test the latest upstream kernel available (not the daily folder, but the one all the way at the bottom) 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-v3.12

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.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  With using Kernel 3.8 and newer sometimes I have a kernel OOPS at startup and it seems it's because I switch off my ATI card.
  I added this line in my /etc/rc.local file:
     echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

  I don't have this bug each time but I guess it depends if this
  previous command is launched before or after that X11's launch. I'm
  using this card: Mobility Radeon HD 4650.

  It seems that this bug has already reported to there: https://bugzilla.kernel.org/show_bug.cgi?id=49531 and https://bugs.freedesktop.org/show_bug.cgi?id=61529
  But I guess it can be interesting to track this bug on Launchpad.
