Since I also have patches to make kthreads freezable, we sometimes have to tell people to add an extra parameter to the create_workqueue call. Once that's done, I believe it all works fine. I keep saying I must seek to merge these patches. I've gotten caught up on trying to get everything ready to merge at once, and confused by what Pavel is and isn't changing :> Pavel, since you're cc'd I might as well ask, am I still right to submit those patches again? If so, I'll try to do it this evening. On a related topic, I've tried to get hotplug cpu support working with suspending, but it looks like more is needed. In particular, the 'dead' cpu still needs state saved and restored, so we're not really gaining anything with the current implementation. If hotplug really killed the CPU and rebooted it, the story might be different.
