I just installed linux 3.7.2 from [testing] on an AMD system and noticed that powernow-k8 is not loaded.

Probably due to this: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=....

Ah... yes. I am confused though, why keep powernow_k8 as a separate module as opposed to an alias?

Meanwhile, linux 3.6.11 works fine. Notice also, that acpi_cpufreq 3.7.2 is fine on a INtel core2duo machine.

Hm, I thought acpi_cpufreq should have been loaded instead, no idea why that does not happen for you. Could you try loading it manually?

Neither acpi_cpufreq nor powernow_k8 is loaded automatically which of course leads to failure of all custom units configuring ondemand governor via sysfs. Manually modprob'ing acpi_cpufreq does work and indeed properly scales down the frequancy, but is accompanied by an info-level kernel message "acpi-cpufreq: overriding BIOS provided _PSD data". So, if the cpufreq driver works OK for other AMD users, I'll happily blame asus... Thanks, Leonid.

Cheers,

Tom
