[Bug 107866] GPU Hangs Abruptly

--- Comment #25 from Denis <denys.kostin at globallogic.com> ---
ok... looks like I reproduced the issue with provided apitrace. But I haven't
ideas - how... I mean, that issue is not straight and stable. I launched
browser with an openGL rendering on it (on of the available demo's) - and then
provided trace - maybe for 3 or 5 times.

And, according to the dmesg, I got 1 hang:

[ 7991.390603] powercap intel-rapl:0: package locked by BIOS, monitoring only
[ 8214.539084] perf: interrupt took too long (3142 > 3137), lowering
kernel.perf_event_max_sample_rate to 63500
[ 8360.400165] [drm] GPU HANG: ecode 6:0:0x85fffffc, in glretrace [20413],
reason: hang on rcs0, action: reset
[ 8360.400167] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 8360.400168] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 8360.400168] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 8360.400169] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
