Hi, I haven't tried any earlier kernel. Problem exists with 2.6.10 and 2.6.11-rc1. System seems to suspend ok. When I press the power button the fans turn on again, the IDE LED seems to flash a little and then stays on permanently. System hangs. Display is still off, so I don't know if there are any kernel messages. All I can do is hit the Reset button. S1 works fine. Under WinXP S3 works. Does anyone see the same problem ? Mathias
