Please send me your > dmesg. I've looked through the motherboard manual and it doesn't look like there are any settings that should affect this. dmesg is at the bottom of this message. > Have you tried the various reboot kernel parameters? You can try the > following. > > reboot=w - Sets warm reboot flag > reboot=c - Sets cold reboot flag > reboot=b - Reboot via jump to BIOS > > and finally if you're really desperate ;) > > reboot=h - do a hard reboot, i think this is does a triple fault Thanks - I wasn't aware of them! I'll see whether that fixes the reboot problem!
