I have the same problem. This is a on a regular PC (not laptop).
acpi0: <ABIT AWRDACPI> on motherboard
pcibios: BIOS version 2.10
Using $PIR table, 8 entries at 0xc00fd7e0
acpi_bus_number: root bus has no _BBN, assuming 0
ACPI-0438: *** Error: Looking up [\\_PR_.CPU0] in namespace,

ACPI-1284: *** Error: , AE_NOT_FOUND
acpi0: power button is handled as a fixed feature programming model.
