I had the CPU frequency scaling working fine on my AMD Turion-based
laptop running SuSE 9.3 and then suddenly it started to freeze every
now and again.

I noticed that the number of processes just increased a lot and then
would suddenly fall back just to increase again.

That is when I saw these messages in my log file:

Lots of them.

So I restarted powesaved and the machine settled down, but the cpu was
stuck at max frequency.

So I tried to reboot and now powersave still does not work.
These are the starup messages after reboot:

Any idea what could cause this?
Thanks
