Your config seems to have CONFIG_PM and therefore CONFIG_ACPI disabled. So the kernel is relying on mptable information. Unsurprisingly on a modern system, that info is probably broken -- since everything would have been tested with ACPI.
Try turning on CONFIG_ACPI and see if that helps at all. -- Roland Dreier <rolandd@cisco.com> || For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/index.html
