In case there was any doubt remaining, it's now been running
3 days, 20 hours with no lockups at all. I haven't seen it
run this long in months.

Either tomorrow or Sunday I'm finally wiping that box
to give it back on Monday, so if there's anything else
you'd like to try, the next 24hrs are pretty much the only
remaining time I have.

One thing I think I'll try is to try and narrow down which
syscalls are triggering those "Clocksource hpet had cycles off"
messages. I'm still unclear on exactly what is doing
the stomping on the hpet.
