------- Comment #7 from [EMAIL PROTECTED]  2008-01-11 00:49 -------
First of all, thanks for working on this!

In this case it does not matter because it fails with the same error message:

[EMAIL PROTECTED]: /root
-> modprobe powernow-k8
FATAL: Error inserting powernow_k8
(/lib/modules/2.6.22.13-0.3-default/kernel/arch/x86_64/kernel/cpufreq/powernow-k8.ko):
No such device
Exit 1

Whatever "device" is needed apparently is broken.  Which module writes the
"rchal: CPU frequency scaling is not supported by your processor." message (see
above)?  That is the first error in /var/log/messages, the powernow-k8 message
comes afterwards.

In case you are wondering, by the way, I have made no BIOS upgrade or changed
any setting in the BIOS at the time cpufreq broke.  Somewhere I read something
about IOMMU (whatever that is) but my BIOS does not have any such option. 
Well, it has worked before with the same BIOS, so it cannot be that anyway, am
I right?

I am attaching the output of dmesg in the hope that it will help to clear
things up...

Many thanks and regards,

Ned.
