Title:
[sandybridge-m-gt2+] GPU lockup IPEHR: 0x54f00006 IPEHR: 0x0b140001

Bug description:
Hi,
I'm victim of freezes (maybe GPU hangs). The mouse can't move. When there is
sound playing, it freezes too.
Sometimes hangs lasts 10 seconds and other times, 10 minutes are not
sufficient nad it requires hardware reboot.
It happens randomly (means that I don't know what caused the freezes) and I
tried but can't reproduced it.
"$ ubuntu-bug xserver-xorg-video-intel" tells me that erport the bug
is impossible and that I have to join ubuntu support.
I saw thoses bugs related but don't know if there is a real link (IPEHR,
chips and kernels are different...) :
