<pre>When I play certain videos in the Chrome browser all a sudden the screen goes
blank. Neither Ctrl-Alt-Backspace (twice) nor Ctrl-Alt-Delete work. I have to
hard reset.
Here is output from /var/log/message
Dec 21 12:45:38 otherworld kernel: [drm] stuck on render ring
Dec 21 12:45:38 otherworld kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Dec 21 12:45:38 otherworld kernel: [drm] GPU hangs can indicate a bug anywhere
in the entire gfx stack, including userspace.
Dec 21 12:45:38 otherworld kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Dec 21 12:45:38 otherworld kernel: [drm] drm/i915 developers can then reassign
to the right component if it's not a kernel issue.
Dec 21 12:45:38 otherworld kernel: [drm] The gpu crash dump is required to
analyze gpu hangs, so please always attach it.
