           Summary: Radeon driver reports EDID errors every 10 seconds
           Product: DRI
           Version: unspecified
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: teufel@cs.uni-frankfurt.de


Created an attachment (id=46512)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=46512)
an excerpt of /var/log/messages with some comments and an example of the output
 to tty1

Radeon driver reports EDID errors every 10 seconds, which causes related log
files increased over 100M in size every day and makes the system hardly usable
because of the output every 10 seconds to tty1 (and ttyS0 in my case).

See also my related LKML message: https://lkml.org/lkml/2011/4/14/661

I get every 10 seconds:
radeon 0000:01:05.0: HDMI-A-1: EDID block 0 invalid.
together with a block of zeroes (only on tty1, see attachment).

OS: Debian GNU/Linux 6.0.1 (squeeze)
kernel: Linux 2.6.38-bpo.2-amd64 (2.6.38-3~bpo60+1)
(it was the same with Linux 2.6.32-5-amd64 (2.6.32-31))

Mainboard: ASUS M2A-VM
Chipset (onboard): ATI Technologies Inc RS690 [Radeon X1200 Series]
aka 01:05.0 0300: 1002:791e

Argh, bad typo:
(it was the same with Linux 2.6.32-5-amd64 (2.6.32-31))
should have been:
(it was the same with Linux 2.6.38-2-amd64 (2.6.38-3))

What I wanted to say: It doesn't matter if the 2.6.38 from wheezy or the
backported 2.6.38 is used, but that may be obvious.

I'm really sorry for that bad copy&paste mistake.

RS690 did not support displayport.  I'm not sure how you have one on your
board.

drm_kms_helper.poll=0 will disable the output polling

As you can see in the corresponding LKML thread, I already know about the
drm_kms_helper.poll=0 option (and use it), but this is just a workaround to
make the system usable and prevent the logfiles of being bloated.
It doesn't fix the original problem (but I appreciate your intention to point
me at this).

I'm sorry. I confounded two boards. The one has displayport, the other one does
not. This one does not. It only has DVI-D and VGA (D-Sub/RGB).
I'm sorry for this mistake.
