Interesting. I have not observed that on my machine here, however I have seen on my dual G5 (and not on the quad) some occasional loss of interrupts for seconds which might be related. Have you verified that you can "fix" it with reverting just the above patch ? I would have more easily blamed the rest of my series than this specific one... Anyways, I'll have a closer look but it might have to wait for tuesday.
