SubjectRe: 2.6.32.1 kernel unable to use more than 2 of 16 CPUs on Intel E5540 (i7)
Date
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.
