https://bugzilla.kernel.org/show_bug.cgi?id=88781 Bug ID: 88781 Summary: black screen when starting X with radeon Product: Drivers Version: 2.5 Kernel Version: 3.17.3 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: serge.yquel@xxxxxxxxxxx Regression: No Hello, Since the 3.17.3 kernel when starting X,I got a black screen with no tty acces,with stable mesa or mesa-git. If i switch to catalyst,all is fine,also after downgrading the kernel to 3.17.2 i can start X with mesa drivers. I did a git bisect and the result is: ffe0245532b98efc4bc0e06f29c51d3f0e471152 is the first bad commit commit ffe0245532b98efc4bc0e06f29c51d3f0e471152 Author: Alex Deucher <alexander.deucher@xxxxxxx> Date: Mon Oct 13 11:51:50 2014 -0400 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.
