            Bug ID: 60510
           Summary: AMD Mobility Radeon HD4650 Screen Corruption with DPM
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.10.0-drm-next-20130705
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
          Assignee: drivers_video-dri@kernel-bugs.osdl.org
          Reporter: yjwong92@gmail.com
        Regression: No

I'm testing out the new DPM patches on drm-next-3.11.

When there is heavy screen updates (i.e. dragging windows around), screen
corruption appears (see video). DPM otherwise works perfectly; system runs
cooler and UVD also works perfectly fine. 

Corruption does not occur with radeon.dpm off.

There is nothing unusual in the kernel logs.

I can provide more info if requested.
