My hardware:
Lenovo Thinpad x220 laptop;
i5-2520M cpu;
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)
My system is Debian testing, kernel 3.13.
When I tried run video (vlc player or youtube in chromium browser) on external
connected monitor(VGA) I got system freeze.
I see this in dmesg:
[ 6456.881715] [drm:ring_stuck] *ERROR* Kicking stuck wait on render ring
[ 6456.881721] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 6456.881722] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 6456.881723] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 6456.881724] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 6456.881724] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

[ 6455.804] [mi] Increasing EQ size to 1024 to prevent dropped events.
[ 6455.804] [mi] EQ processing has resumed after 317 dropped events.

server's resources.
What additional information I have to show?
Thanks.</pre>
