This is a real bug that crashes my laptop without any kind of provocation. It is undeniably a bug in i915, and I've clearly described it in my patch. If you dont like the patch, I'm open to any suggestions you have for an alternative solution. My goal here is to make i915 better, but it's difficult when communication only goes one way. Thanks, Sultan
