          Priority: medium
            Bug ID: 66714
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Mobility Radeon HD 5650 doesn't boot with kernel 3.10
                    (and newer) when using radeon.audio=1
          Severity: critical
    Classification: Unclassified
                OS: Linux (All)
          Reporter: mail@3v1n0.net
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: XOrg CVS
         Component: DRM/Radeon
           Product: DRI

If I enable the HDMI audio using the Mobility Radeon HD 5650 card with kernel
3.10.0 (or newer), I get a kernel oops that prevents me to boot.

This is a regression, since everything is fine with kernel 3.9.0.

Also, when I enable the switchable graphics in the bios, the notebook boots but
as soon as I use vgaswitcheroo to switch to the discrete card, I still get a
black screen and the system can't be used (when restoring the integrate card,
it goes back to work).

This is the kernel failure I've found:
