Hi again, I believe I've been able to resolve this by performing a BIOS update on my motherboard. I confess ignorance about how all of this works, but it would appear that my motherboard didn't know enough about my CPU to use it correctly. Before the BIOS update, /proc/cpuinfo and other tools would just tell me that I was using an unknown or generic (I can't remember the wording) AMD processor; after the update, it correctly identifies my "AMD Phenom(tm) II X6 1055T Processor". Also, before the update only 3 frequency steps were available: 2.80 GHz, 2.20 GHz, 800 MHz; Now a fourth is available and all of them are being used: 2.80 GHz, 2.20 GHz, 1.50 GHz, 800 MHz. And finally, I am not receiving the mentioned messages in me kern.log anymore.
