Bug Description

There is a problem with ECS A740GM-M Motherboard (integrated radeon graphics). Even though there is no monitor connected to the DVI port the drm/radeon module dumps every teh seconds an EDID to the kernel logs and onto terminal sessions. This is valid since Ubuntu lucid and still exists in latest Ubuntu natty kernel.

There is a patch for this problem proposed for upstream kernel.

See https://lkml.org/lkml/2011/7/20/38

I've backported the patch to Ubuntu Natty and it has been successfully tested by Stephen_m64 (see http://ubuntuforums.org/showthread.php?t=1607778).

You will find the test kernel in https://launchpad.net/~rdratlos/+archive/ppa-asus-m2a-fix.

The abovementioned patch is included upstream in kernel 3.1-rc1 and has also been cc'd to the stable kernel maintainers for consideration. A PPA of this kernel is available at http://kernel.ubuntu.com/~kernel-ppa/mainline/
