Bug Description
Binary package hint: acpi
I am using a Foxconn A7GM-S 2, with the newest BIOS: ID 872F1P02, Version 08.00.14 - At boot up, I get the following message:
####
[ 5.824140] [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.

This happens in both 32 and 64 bits. This is not a kernel bug, but a BIOS bug. This has been well established. See here for a more generic bug report. See also below, it seems as if Foxconn is currently (2009 mid August) working on this.

Just an update: I reported this upstream and the bug report got quickly rejected as "invalid".
