With drm-fixes -
3.7.0-rc2-70305-g96fb1a2
I see -
powernow-k8: this CPU is not supported anymore, using acpi-cpufreq instead.
Which seems to be working Ok, so closing.

Actually this should be solved by the following commit:
e4df1cb: cpufreq / powernow-k8: Remove usage of smp_processor_id() in
preemptible code
Cheers,
Hedi.

Can you please test the current mainline (v3.8-rc5 as of today)?
A few patches have been applied to it affecting this area.

What's the problem? Did you get a call backtrace or cpufreq does not work for
you? And if there is a problem, can you please test the current mainline as
comment #4 has suggested? Thanks.
