--- Comment #33 from queryv+fd@gmail.com --- I'm also experiencing this issue with my 6870. I decided to attach a second monitor yesterday and immediately noticed that my card went from idling at around 45°C to a steady 55°C.
'watch cat /sys/kernel/debug/dri/0/radeon_pm_info' shows that I'm stuck at power level 2, even when running a game like Xonotic. I get the same 'bash: echo: write error: Invalid argument' error if I try to force a performance level as well.
Using 3.11-rc5 + the drm-next-3.12-wip branch.
