No idea at this point. It doesn't happen on the albooks I could test with here... Can you send me a snapshot of a corrupted screen ? Does it still happen if you disable dynamic clocks ? (radeonfb.default_dynclk=-1 on the kernel cmdline and Option "DynamicClocks" "false" in X if you are using X.org). And if you disable accel in X ? (Option "NoAccel" "true") Ben.
