Description Justin Newman 2009-07-22 17:25:37 UTC
/var/log/messages returns the following error:

"[Firmware Bug]: powernow-k8: Your BIOS does not provide ACPI _PSS objects in a way that Linux understands. Please report this to the Linux ACPI maintainers and complain to your BIOS vendor."

I suspect that this is a firmware bug, but I've been in contact with BIOS and I thought it would be appropriate for both parties to be aware. As I can recall, it worked fine with previous BIOS versions.

Boo for lack of rereading and lack of edit button. :/

right.
And if you are running the latest Linux kernel release, you will see
"No compatible ACPI _PSS objects found. Try again with latest BIOS."
instead.
this is not a Linux kernel bug. Reject it.
