dmesg

I have Debian testing on Acer Extensa 5220 with integrated graphic controller
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) [8086:2a02] (rev 03)
using i915 driver.
When I run the program glmark2 the video card stops working (the screen goes black).
In the dmesg there are messages like
[drm] stuck on render ring
[drm:i915_error_work_func], resetting chip
[drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x53b0000 ctx 0) at 0x53b15fc
[drm:i915_reset] *ERROR* Failed to reset chip.

No difference if using mesa from testing or experimental repository.
