For example, kernel/softirq.c:cpu_callb= ack() ? I'd they should be affected as well. For me, I guess I haven't run into them because xfs is enough to freeze the box ;) As for Rafael, I don't know why he isn't seeing that... I haven't been able to test this patch on my quad powermac so far unfortunately, been sick and away from the machine. I'll probably be able to test tomorrow. > I think we need a general "cpu_down() after freeze" implementation, Yeah, I'd think so. > this is what > Gautham and Srivatsa are working on, right?
