--- Comment #7 from Adam Hirst adam@aphirst.karoo.co.uk --- Created attachment 91795 --> https://bugs.freedesktop.org/attachment.cgi?id=91795&action=edit 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.
