          Priority: medium
            Bug ID: 70439
          Assignee: dri-devel at lists.freedesktop.org
           Summary: Mobility 4570: System freezes after ~5s of enabling
                    audio via xrandr
          Severity: major
    Classification: Unclassified
                OS: Linux (All)
          Reporter: CE.Mohammad.AlSaleh at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: unspecified
         Component: DRM/Radeon
           Product: DRI

Kernel: 3.12rc3

Enabling audio by executing:
  $ xrandr --output HDMI-0 --set audio auto

This causes the system to fully freeze after seconds forcing me to hard reset.

Audio actually works in those few seconds.

Bug present with and without DPM.

-----

I don't know how to gather more info with such freezes. Feel free to point me
into the right direction.
