judging from the processor name string it looks like your BIOS doesn't
program the processor name properly which could mean that you need
to check whether your motherboard supports Phenom II CPUs and if so,
upgrade your BIOS. This could also explain the mis-calibration issue.

Also, is this a 32-bit kernel you're booting?
