Hi,
I just tried the DPM support out on a E-450 APU (HD6320) and it did not work like expected. In the terminal everything seemed ok but when I started a display manager, the screen showed garbage and the system basically locked up. The radeon and drm related parts of the syslog are below.
I saw, that you updated the patches, therefore I tried out the branch drm-next-3.11-wip-2 and I got, additionally to the problem mentioned in my first e-mail, the following warning:
