Hi,
Just have time to try 2.6.30_rc1 and had an oops during powernow-k8
initialization.
I'm giving the config file and full dmesg output.
The cpu is an AuthenticAMD Athlon 64 X2 Dual Core Processor 4800+,
family 15 model 107

I'm still having this problem with today's 2.6.30_rc3.
There's a patchset from "Rusty Russell: cpumask: avoid playing with
cpus_allowed in powernow-k8"
sent on 13/04/2009 that I suspect it may be the solution but I didn't
have time to give it a try.
Regards,
Hi,

Just read what the message says: it is not a kernel bug but simply your
BIOS is missing the _PSS objects on which powernow-k8 relies. I'm pretty
sure you had similar message in earlier kernels but it was a simple
warning then.
Is it possible to upgrade your BIOS? If you're lucky, it might've been
fixed :).

Yes I'm aware about the firmware bug but the backtrace shouldn't appear
on the kernel log buffer, and yes I was having the firmware message with
2.6.29 too but not with that backtrace.

Why not?
For the reasoning behind why you get a backtrace instead of simple
warning see
