i915_error_state_decoded

While either cycling through internal/external TFTs or switching back from the
console, GNOME3 crashed in the sense that the Shell and Mutter went away and
the keyboard no longer worked (probably none of the windows had focus). I did
not see the Shell and Mutter disappear so it happened either while I was
looking at the console or when switching.

I was still able to use the pointer and e.g. switch tabs in the gnome-terminal,
as well as open a new terminal from the menu, but could not switch focus
between them by clicking.

This is from dmesg:

[54282.564118] [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed...

[54283.072037] [drm:i915_reset] *ERROR* Failed to reset chip.

The batchbuffer was:

(the full i915_error_state is attached).

Please note that shortly before that, the internal TFT of the ThinkPad had
stopped working after a suspend to memory resume - backlight was still on, but
it was just blank.  I filed this as Debug Bug #694946:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=694946

The other times I had this problem (happens 10-30% of the time) I rebooted
rather quickly in order to get the notebook back to work.
