          Priority: medium
            Bug ID: 66551
          Assignee: dri-devel@lists.freedesktop.org
           Summary: System hang when DPM  enabled on rs780.
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: octoploid@yandex.com
          Hardware: Other
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

I've tested the new DPM code (git://people.freedesktop.org/~agd5f/linux
drm-next-3.11) on my rs780.
I can reproducible hang my system by just copy/pasting
a big document under LibreOffice. During the hang the keyboard is 
unusable and the mouse pointer only moves noncontinuous and jerky.
Hitting the reset button is the only remedy.

By disabling DPM the problem goes away.
