Thanks.  Is this a regression?  What are you doing when this happens?

Does
	mount -t debugfs debugfs /sys/kernel/debug
	cat /sys/kernel/debug/dri/0/i915_error_state >error_state

produce any output?  Please also attach output from

	reportbug --template linux-image-$(uname -r)
	reportbug --template xserver-xorg-video-i915

Thanks,
Jonathan
