I have noticed this behaviour on at least one machine. If I shutdown the machine with apm power off, the filesystem is dirty and has to been checked on the next reboot. It seems, the power is cut too fast. I don't have any problems with reboots. It seems the drive doesn't have the time to write the superblock back to disk.
I simply put a DELAY(4000000) in the apm_power_off() routine and the problem fades away. Any thoughts on doing this a configurable option? It doesn't break anything, it only takes a few seconds longer for the machine to power off. The drive is a Maxtor Diamond Max (90432D2) 4GB IDE drive in an Asus SP98 board.
