Hmmm. It looks like the TSC interpolator is deadlocking. I'll try to dig in and hunt that one down (although forgive me if I don't get back to you until sometime next week).

New timeofday subsystem: Lockups

John, Nish, others:
I'm not sure whether this is an issue with John's TOD patches, John's
NTP rework, or Nish's softtimer patches, but something in this
combination seems to be locking up my system frequently. Often, it will
completely hang during boot, and it periodically hangs while starting X
or even just under normal (unstressed) use.
During several of the boot-ups, the NMI Watchdog has caught lockups.
Here is the output of one of those lockups (hand-copied, so hopefully no
mistakes):
