Hi, During a hibernate cycle on my G5, while machine was powering down after saving the image, I just had a NULL dereference in clockevents_program_event when accessing dev->mode, dev was NULL.
Unfortunately the machine rebooted before I was able to write down more than the fact that it was called from tick_program_event(); the problem doesn't seem to be easily reproducible. From what I can see when doing the same thing, the shutdown attempts to offline all CPUs. Because the snapshot was actually saved to disk and the machine was shutting down I guess that the it happened at that time, but I have no idea what else to do to debug this. I have | CONFIG_HIGH_RES_TIMERS=y | CONFIG_NO_HZ=y in this config. johannes
