terminal output and backtrace

When running Khronos Webgl test suite there is an occasional crash and gpu
hang. This is not 100% reproducible with one test, sometimes it finishes whole
test run OK, sometimes it hangs really fast. Running glsl functions subtests
few time is a row reproduces it here always.

[  534.984024] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...
GPU hung
[  534.984036] [drm] capturing error event; look for more information in
/debug/dri/0/i915_error_state
[  534.987135] [drm:i915_reset] *ERROR* Failed to reset chip.

from terminal, full output and backtrace attached:
i915_drm_batchbuffer.c:187:i915_drm_batchbuffer_flush: Assertion `ret == 0'
failed.
