--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
The buffer it was writing to at the time of the suspected hang is odd sized -
but the error state indicates that the GPU was not hung nor had reported an
error, so I was a little surprised that it decided to report a hang and had
hoped that there was a precursor in the log.

Mika, mind just confirming that the hangcheck code hasn't gone completely mad?
And if you can not spot a problem, let's file this as impossible until proven
otherwise.

Mathieu, please keep an eye for further hangs.
