Created attachment 93135 One potential idea I tried to look through our gen7 page flip code. Looks like everything's according to spec, except we allow the MI_DISPLAY_FLIP to straddle two cachelines. This patch fixes that. Worth a shot I suppose even if the hanging flip in the error state didn't hit this. There were flips in the ring that would have hit this though.
