Hi,

this is on Ubuntu Trusty, I attach the gpu crash dump as told in kernel
messages:
[48264.487804] [drm] stuck on render ring
[48264.487809] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[48264.487810] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[48264.487811] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[48264.487812] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[48264.487813] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

cheers,
Andreas
