Matthieu Baerts, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please just make a comment to this.

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.
WORKAROUND for kernel versions < 3.12: Note that I no longer have this crash
if I remove this line from /etc/init/lightdm.conf :
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
With the Kernel 3.12, we always have this crash even if we disable
this card before launching X11.
