System reboots after shutdown after some time
Since I switched to the 2.6.11.* kernels, every time I shutdown my system, it boots again after some time. I usually notice this when I shutdown the system in the evening: The next morning the system will be booted, although it _clearly_ shutdown (no fans to hear, no harddisk activity, blank display, no LEDs blinking).
I cannot think of where to start with debugging. It happens with version 5 and 8 of the 2.6.11 kernel lines (I did not try any other though). Older kernels and Windows do not have that problem.
Does anyone have a solution for this problem or knows what can make a PC boot up "on its own"?
Thank you for your time!
