Loïc, the GM45 should reset itself when it detects an error, but in your
dmesg I can't see any error from drm (normally it's either "Hangcheck
timer elapsed... GPU hung" or "render error detected"). You can increase
the verbosity and display any messages from a reset with drm.debug=0x02
as kernel parameter.

It would be great if you can test the latest drm-intel-next kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/ and when
this happens, ssh in and grab /sys/kernel/debug/dri/0/i915_error_state,
/var/log/Xorg.0.log and the output of dmesg (preferably with
drm.debug=0x02).
