Created attachment 48390
Part of dmesg with power states
It's a Sapphire Radeon HD5670 512MB GDDR5. DRM reports 5 power states, but low profile won't use #4 (closed), wich is the 2D profile, nor does dynpm. All kernels with Evergreen pm support are affected by this (possible) bug, including 3.0-rc4.
cat /sys/class/drm/card0/device/power_profile
