[Bug 364156] Re: powernow-k8: BIOS does not provide ACPI -PSS objects in a way that Linux understands

[David Gaarenstroom]

@Pyoverdine:
You should look in your BIOS at the CPU setting for something called "Cool 'n' Quit", "Dynamic Clock" or "Frequency Scaling" that should be "Enabled". Do not use "Auto", because that may only work on Windows.  If you you cannot find such an option, you may have an option "AM2 Boost" instead, please disable that (only if there is no C 'n' Q option)...

"Your BIOS does not provide ACPI _PSS objects in a way that Linux
understands" almost always means that Cool 'n' Quiet has been disabled
in the BIOS. This kernel message also isn't really an error, it just
tells that the kernel will not use CPUFREQ powernow-k8 support because
Cool 'n Quiet has been disabled, so it's doing exactly what is
requested.

Please verify that C 'n' Q has indeed been disabled in the BIOS, and
then determine what you want. If you don't want Cool 'n' Quiet you can
ignore this message (powernow-k8 has been built-in in the kernel so you
cannot prevent this message from being displayed).
