Thanks.  Could you please try this path:

http://people.FreeBSD.org/~bruno/powernow.c.pending_bit_stuck.diff

cd /sys/i386/cpufreq
patch < /path/to/powernow.c.pending_bit_stuck.diff
cd /sys/modules/cpufreq
make
make install
make clean

then reboot and please report if that help with the powerd problem.

Cheers,
