Another GPU crash dump

I just experienced the GPU crash again and attached the GPU crash dump.
Unfortunately, I was not able to catch the backtrace of kwin.

The kernel said
Aug 03 13:12:00 r-schnelltop kernel: [drm] stuck on render ring
Aug 03 13:12:00 r-schnelltop kernel: [drm] stuck on blitter ring
Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU HANG: ecode 0:0xf4e9fffe, in
Xorg [955], reason: Ring hung, action: reset
Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Aug 03 13:12:00 r-schnelltop kernel: [drm] Please file a _new_ bug report on
bugs.freedesktop.org against DRI -> DRM/Intel
Aug 03 13:12:00 r-schnelltop kernel: [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Aug 03 13:12:00 r-schnelltop kernel: [drm] The gpu crash dump is required to
analyze gpu hangs, so please always attach it.
Aug 03 13:12:00 r-schnelltop kernel: [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Aug 03 13:12:00 r-schnelltop kernel: [drm:i915_context_is_banned] *ERROR* gpu
hanging too fast, banning!
Aug 03 13:12:02 r-schnelltop kernel: [drm] Enabling RC6 states: RC6 on, RC6p
off, RC6pp off

I have to reboot now, something else seems to hang as well (my current suspect
is d-bus) and the machine is mostly unusable.


The software versions changed to:
KWin 4.11.9
Mesa 10.2.4
xserver-xorg-core 1.16.0
xserver-xorg-video-intel 2.21.15
Kernel 3.15.3 (vanilla upstream)
