Dave Arlie has a patch that converts the DRM_INFO to DRM_DEBUG, which sticks a
muffler on that. Posted on lkml yesterday, it doesn't fix the problem but
does shut it up. The actual statement that causes that I put in every kernel
back to 2.6.27-rc1, and they all do similar reports, so this is a long
standing, and apparently mostly harmless bug. I have seen zero screen
corruption other than the terminals scrolling leaving trash '_' behind and
has been for at least a year.
Thanks Jaswinder.
