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. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
