Sadly, I have no idea how to avoid this. What happens when the pm-timer wraps around while the processors are in C3 sleep state? How is this wrap detected at all? Is there anything I could put into amd76x_pm? It's no problem detecting a timer wrap there. -jo -- -rw-r--r-- 1 jo users 62 2007-05-13 21:55 /home/jo/.signature
