In this case since the issue was papered over all the kernel up until 3.7, I think repapering is the answer for now. I have a novel idea maybe someone could spend some time working out what is broken in private on a test box instead of making everyone who runs 3.7 and 3.8 on ILK deal with it. I of course know this won't happen and I'll be reverting patches from you guys that cause Ironlake flakyness for ever. Dave.
