Is ULV standing for Ultra-low voltage? If so, isn't this option something meant to be applied on APU only?
Mmm don't know. Haven't digged more, but my GPU (R7-265) is running hotter than before, always around 39°-40° (even without any running application). With the kernel in debian sid, 3.16.X, I can see low temperatures in idle.
I'm unable to trigger this warning booting up with radeon.dpm=0, so I think is something related to power management.
