At the same time, the whole "incapacitated by the rt throttle long

skip_clock_update issue does make me go "Hmmm..". It would certainly
explain Dave's incomprehensible watchdog messages..
Dave's first email mentioned that he had panic on softlockup enabled,
but even with that off the box wasn't recovering.
In my trinity runs here, I've gotten softlockup warnings where the box
eventually recovered. I'm wondering if some of the "bad" commits in
the bisection are really false positives where the box would have been
able to recover if we'd killed off all the trinity procs and given it
time to breath.
