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.
Well, according to my journalctl log, it seems to always be triggered after a power state switching. It doesn't do it from boot (power state 0) to performance (power state 1), but it is later. Strangely, I see a Sep 25 20:28:28 Xander kernel: switching from power state: Sep 25 20:28:28 Xander kernel: ui class: performance ... Sep 25 20:28:28 Xander kernel: switching to power state: Sep 25 20:28:28 Xander kernel: ui class: performance
Why would it try to switch from power state 1 to power state 1 (the same power state)? And why is it at that moment the problem arises? I'll have to do more tests to see if this behaviour happens each time.
