Bug ID: 86571
Summary: Kernel 3.17.3: drm/radeon: fix speaker allocation
setup --> cannot $startx
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Driver/Radeon

Since Linux 3.17.3 calling $startx will freeze or reboot my system.
I have isolated the following commit as the cause of my problem:
commit ffe0245532b98efc4bc0e06f29c51d3f0e471152

drm/radeon: fix speaker allocation setup
commit 4910403836ded89803fab201d4b5caaa85de3a89 upstream.
If the sad_count is 0, set the hw to stereo and change
the error message to a warn. A lot of monitors don't
set the speaker allocation block.
