Well, in theory, the interrupt would be generated *before* the hardware goes to RC6; when idle, I'm not exactly sure what the hardware would be doing to generate interrupts. > I'd say you've found the clue here -- I'm a lot happier with going with > your patches now (and I was pretty happy with the gen7 side before). > I'd just like to not mess with gen6 unless we've got missed irq bugs > there to fix. Yeah, knowing that there might be interrupt funnies due to RC6 goes some way to explaining why just avoiding RC6 helps. I wonder if any of this might explain the RC6 issues we see on SNB on some hardware, and whether we should give this a try... I know, grasping at straws, but still, it's about all we have at this point. -- [email protected]
