https://bugzilla.kernel.org/show_bug.cgi?id=97561 Bug ID: 97561 Summary: Regression: Issue with ATI HD 6570 (possibly others) HDMI output Purple Line Product: Drivers Version: 2.5 Kernel Version: 4.0 and above Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: fr0@xxxxxxxxxxxxxxxxxx Regression: No Hi, First ever kernel bug report so apologies for possibly getting it wrong. Both Linux version 4.0 and 4.1-rc now display a vertical purple line on the far left hand side of the screen. This only happens when using HDMI output and seems to be related to HDMI audio. Happens with MESA 10.5 and MESA 10.6 devel, happens on both Arch Linux and Linux Mint (using a mainline kernel). Problem does NOT happen on Linux 3.19.3 and earlier. Image of problem: https://lh3.googleusercontent.com/-i_dXYiwJNBE/VUE1pbSid4I/AAAAAAAAEus/uAfOCER4PSE/s912/IMG_20150429_203014.jpg Very similar bug: https://bugzilla.kernel.org/show_bug.cgi?id=43154 (resolved, but appears to be happening again). lspci: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Turks PRO [Radeon HD 6570/7570/8550] Giving this command resolves the problem - hence I think it is related to the audio output part of the dri driver and is very similar to the bug linked too above: xrandr --output HDMI-0 --auto --set audio off I am happy to provide logs of anything - please let me know what you need. I don't want to take a wild guess and provide everything.
