GPU crash dump
Using Xubuntu 14.04 (3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:51:08 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux).
Screen freezes and doesn't recover. Mouse pointer can be moved, but no action
is possible. Switching to console (Ctrl+Alt+F1) takes some time but finally
works.
Syslog says:
kernel: [41262.418736] [drm] stuck on render ring
kernel: [41262.418745] [drm] GPU crash dump saved to /sys/class/drm/card0/error
kernel: [41262.418747] [drm] GPU hangs can indicate a bug anywhere in the
entire gfx stack, including userspace.
kernel: [41262.418749] [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
kernel: [41262.418751] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
kernel: [41262.418754] [drm] The gpu crash dump is required to analyze gpu
hangs, so please always attach it.
