--- Comment #9 from Andre Heider a.heider@gmail.com --- Maybe unrelated to this bug report, but with today's Linus' master (04012e3076943f17c8cfc77a196701c8f0b8964f) the only suspend/resume issue left is that I get:
[drm:rv770_stop_dpm] *ERROR* Could not force DPM to low.
in dmesg upon resume.
That is before the 'ring' and 'uvd' messages. It seems harmless, I didn't notice any problems. It can switch power levels later on, play videos via uvd... it just seems to try to do something with dpm too early in the resume process.
