I think actually the whole xtime initialisation xtime.tv_nsec = (INITIAL_JIFFIES % HZ) * (NSEC_PER_SEC / HZ); is bogus. INITIAL_JIFFIES should not be connected to any actual time, so this should really just be xtime.tv_nsec = 0; I'll try to do a patch later on, and see what happens. Have to do some work-related things now.
