Yeah, dumping some interrupt regs if the isr returns IRQ_NONE sounds good. For a start just dump everything that the isr itself reads out or writes back - I think we can ignore subordinate interrupt sources in i915 for now. And please mind the guy with bad memory and tell us which chip you have again? Yours, Daniel -- Daniel Vetter Mail: daniel at ffwll.ch Mobile: +41 (0)79 365 57 48
