Randomly ati-drivers make kernel oops and only thing is obviously to reset the machine. i am running kernel 2.26.30-r5 on a mainly stable amd64 distribution with only a few ~amd64 packages (amarok and other apps, no system package) here follows the log of the kernel oops. As you can see it segfaults in the opengl screensaver.
