After installing a Phenom II X4 processor (replacing a single core Semperon) I am getting these messages on the console and in dmesg:

I had an AMD box that started reporting time going backwards. Turned out the heatsink was loose because the retainer tab cracked off - cpu continuously cycled thru overheat, throttle down, overheat, throttle down, etc.
