    Very strange. I threw in an output line counter into the printk code() ... if I
    disable the timestamps for the first 30 lines, then everything is good (so the
    basic timestamping code does still work on ia64). But I would have thought
    that Ingo's delay until sched_init() ought to be long enough too. Clearly I
    need to figure out exactly what needs to be initialized to prevent the
    hang/crash.
