            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)

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.

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.

Thanks !
