Hrmmm. Are you seeing something like:
Loosing too many ticks! TSC cannot be used as a timesource. (Are you running with SpeedStep?) Falling back to a sane timesource.
in your dmesg?
I just realized that in clock_fallback() from my lost-tick-speedstep-fix we don't re-calibrate loops_per_jiffies. The conversion from cycles to loops should be pretty close, but that might need some additional work.
Hrmmm.. -john
