It changes type of bad effects when varying cpu speed from slow and random line redraw to flashing big white random patterns. And I've seen similar behaviour with voipac pxa module where framebuffer with cpu set to 416Mhz moves accidentally some pixels to the right under cpu load. Moreover several speed changes leads to "hda: lost interrupt" on spitz. -- watashi |v|3+@n Cyril Hrubis watashi.metan@gmail.com http://atrey.karlin.mff.cuni.cz/~metan/
