Package: linux-image-2.6.16-2-xen-amd64-k8
Version: 2.6.16-14
Severity: normal

Hi,

after switching to a xen-kernel the frequency scaling of my AMD Athlon64 
CPU stopped working. Instead my syslog is filled with following messages:

Jun 16 15:30:03 harry kernel: powernow-k8: fid trans failed, fid 0x2, curr 
0xc
Jun 16 15:30:03 harry kernel: powernow-k8: transition frequency failed
Jun 16 15:31:00 harry kernel: powernow-k8: fid trans failed, fid 0x2, curr 
0xc
Jun 16 15:31:00 harry kernel: powernow-k8: transition frequency failed

It seems that there is a patch[0] available and according to the 
posting[1] of another person having that problem it fixes the issue.

Have not tested the patch yet but I am willing to test prepared packages
when someone integrates the changes.

Regards,
Uwe

I'll close this bug for now. The integration of the Xen Dom0 code is
problematic for Debian since the code is still not merged into the
standard Linux kernel. It's planned that Dom0 patches will be provided
for Squeeze again. If you can still reproduce the problem with the
upcoming Debian kernel, please reopen the bug.

Cheers,
