>Description:
FreeBSD 5.3-5.4 and motherboard Asus P4SP-MX hangs on reboot. Last message:

Syncing disks, vnodes remaining...1 1 1 0 0 done
No buffers busy after final sync
Uptime: 19h20m46s
Shutting down ACPI
Rebooting...

and hang. then hardware reset only (
Hangs with GENERIC kernel. Hangs when boot from CD. I tried with/witout ACPI, changed all bios setting, tried early bios version. Including "option BROKEN_KEYBOARD_RESET" dont work.

But "shutdown -p now" work fine with ACPI.
