[x86_64] Exception when using powernowd.

From: Kyuma Ohta
Date: Fri Sep 02 2005 - 12:19:00 EST

Hi,

I'm using MSI K8T Neo2 (VIA K8T800 chipset) and Athlon64 3000+
with linux x86_64 2.6.13 kernel and Debian/sid.
When enable powernow-k8 (i.e. using powernowd,cpudyn) to
saving power, some process is down by null protection and
system is unstable.
Then disabling powernow-k8,and reboot, system is very stable.

I attach any log,please give me a advice.

Regards,
Ohta.
