Hi,

We have a new webserver with two Opteron 244 CPU's which support the
Powernow powersavings technologie. We use FreeBSD 5.4 stable with the
built-in cpufreq and powerd options and we have some difficulties to get
it running longer than 2 seconds.

If we enable powerd in rc.conf (powerd_enable="YES") and we reboot the
machine, the machine hangs after about two seconds after the boot
process is at that stage during booting. So we disabled that option. The
server now starts as it supposed to do, but if we start powerd, the
server hangs again after two seconds.

What settings other than the default settings do we need so that the
server is not crashing upon starting powerd? Does anyone use Opterons
with powernow enabled? If so, what is their config?

Thanx in advance,

Justin Suyk.
