Have you tried reducing HZ to 100 (put kern.hz="100" in
/boot/loader.conf and reboot)?
Are you running powerd? Look into "sysctl hw.acpi" and "sysctl
debug.cpufreq"....
Regards,
Thanks for the ideas Chuck. I lowered kern.hz to 100 as you suggested
(does this affect the kernel's ability to track time in milliseconds?
ie. if I want to run a benchmark using the 'time' utility?). And the
output of the two sysctl queries is posted here:

I'm not very familiar with acpi, so if you see anything that could be
optimized, I'd appreciate the feedback.
