Comment 11 for bug 404428

i just tested mesa with r600 enabled on my own and it's probably better to keep it disabled, because when running the stock karmic kernel and calling a 3D app (and therefore Mesa) X is starting to hang. so only the combination of r600 enabled Mesa and matching DRM modules should be allowed and therefore this bug should be "Won't fix", unless there is a simple way to disable r600 in Mesa at runtime after checking for DRM support.
