[Bug 946899] Re: [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung

[Tristan BENOIST]

Hello,

I have the same problem here with a freeze of all the screen except the
cursor.

I have nvidia optimus handling a Geforce 520M and an intel video chip.

uname -a :
3.5.0-26-generic #40-Ubuntu SMP Tue Feb 26 19:57:24 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

dmesg :
[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
[drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off
atl1c 0000:07:00.0: vpd r/w failed.  This is likely a firmware bug on this device.  Contact the card vendor for a firmware update.
