[Bug 43272] New: pink/purple line displays to the left of the screen

           Summary: pink/purple line displays to the left of the screen
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.4.0
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: low
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: damoxc@gmail.com
        Regression: Yes


Ever since the upgrade to 3.3 I've had a pinkish purple vertical line down the
left hand side of the screen that's probably 2-5px wide. It happens early in
the boot process (I imagine as soon as KMS in engaged). I've had a look through
the boot log but can't see anything suspect, but then I don't really know what
I'm looking for.

Anyone who can give some help in where to look for additional information to
help resolve this would be most appreciated.

I should add this is a Sapphire Radeon HD6950 plugged into a Samsung HD TV via
a HDMI cable.

Looks like I do, I'll have to wait until I get back from work to see whether
that fixes it, thanks!

Just a note that might help debugging: I see a purple vertical line on the left
hand side of the screen when I send AVI InfoFrames to a DVI monitor.

Also, when I do this, some modes don't work, other modes look really buggy.

The purple line is caused by setting the digital encoder into HDMI mode and
then not sending the proper infoframes.

Hi,

Setting radeon.audio=0 has resolved the problem. I still had radeon.audio=1 set
in a modprobe.d file left over from when I had a HD4870.

Thanks for the help!
