dmesg output

This is a whole swathe of dmesg output, to do with the power-level changes when
using UVD. I know for a fact that *some* of these correspond to correct
rendering cases. When checking dmesg immediately after a successful run, the
most recent set of power messages was identical to the previous.

I'll disable dpm and test further.
