As always this appears to be a BIOS problem (bug?)
As soon as you change the BASECLOCK setting, all C states are withdrawn.
I think it's really idiotic, and I am really going to try to enable them
anyway.
Interesting fact: the system uses almost exactly the same amount of
power when C states are enabled by the BIOS and when they are disabled.
Makes you wonder whether they actually do something at all. The linux
counters really say they're called, anyway.
So if you don't want a power-wasting board, don't buy a Gigabyte EX58-UD3R.
