Looks like fallout from a missing ILK rc6 workaround - it looks like the
write to the ring tail never landed and so the command streamer hung.
See https://bugs.freedesktop.org/show_bug.cgi?id=55984 and
http://cgit.freedesktop.org/~danvet/drm/log/?h=ilk-wa-pile of which I
think
http://cgit.freedesktop.org/~danvet/drm/commit/?h=ilk-wa-pile&id=0d5fed2de763b49bb1a90140758153481f043757
is the missing ingredient.
