PCI: Not using MMConfig
PCI: PCI BIOS revision 3.00 entry at 0xf0031, last bus=8

mtrr: corrected configuration.

And here system stops.
Linux can boot normally with "acpi=off" option, but there is a warning message
in dmesg:
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.
My AMI BIOS version is from July 2008.
Steps to reproduce:
Launch 2.6.26.x or 2.6.27-rcx kernel with ACPI on Asus M51TR notebook.
