--- Comment #5 from Chris Wilson <chris at chris-wilson.co.uk> ---
Ah, that's interesting. I had interpreted it that it became slow during the
session for which I suspected a GPU hang and subsequent use of reads/writes
through the GTT. Nothing looks unusual in the log.

Can you please have a look with top to see if there is abnormal CPU loading and
if X looks more busy than usual, see if 'sudo perf top' will pinpoint the
culprit? What will also be useful, if it doesn't mask the issue, would be
building xf86-video-intel with --enable-debug=full and sending me the
Xorg.0.log file for the affected session.
