Yes,
it all points to either HPET having high latency because it is dealt
with in SMM mode or the hardware is generally spending hundreds of
milliseconds in SMM doing whatever it thinks it is doing, which delays
normal system processing considerably.
Btw, Mike, you could try to boot with hpet=disable so that you can
fallback to the acpi_pm timer and see whether you can see delays then
(look for the last message "Switching to clocksource ..." in dmesg to
tell you what timer you're falling back on - /proc/timer_list should
have that info too, though).
Thanks.
