Thanks alot for testing. Unfortunately the versions you're using are
known-broken. Please retest with the latest&greatest (currently libdrm
2.4.20 and xf86-video-intel 2.11). Also, when the gpu hangs (as indicated
by the hangcheck time elapsed error in the dmesg) always grab an
i915_error_state (from the dri directory of the debugfs filesystem). That
file contains the a dump of the gpu state when it died with all the
necessary info to debug such a hang (the dmesg only tells that the gpu
died, but misses all the other needed info).
