[Bug 231534] Re: Hardy x64 on AMD Turion not CPU scaling properly

[David Gaarenstroom]

As for the *original* bugreport, this dmesg output:

Jun 26 20:55:57 lappy kernel: [ 494.227246] powernow-k8: BIOS error - no
PSB or ACPI _PSS objects

Tells me that your BIOS is broken. This cannot be fixed by the Linux
kernel.

Please verify whether there is a more recent BIOS for your system, perhaps your manufacturer has already released a fix. If not, you could request them to do that. Also, perhaps there's a custom ACPI "DSDT" for your system available for Linux that provides a PSB or _PSS table. There are some HOWTO's available that will help you do that.
It could also be that a BIOS option is blocking the PSB or _PSS objects, something in the line of "intelligent power managment" or so. My Asrock motherboard has such an option, I don't remember what it is called.

(I'm not immediately switching the status of this bugreport to "Invalid"
as I will wait for your feedback first)


As for all the noise in this bugreport, please fill in your own bug reports...
