Having mounted firewire disks prevent programmable reboot. System shuts down and console shows the last "uptime" message but newer resets or reboots. Reset key or power cycling is necessary to reboot.

In this case, system has UFS basic partitions in /dev/ad* disks and two ZFS pools, one totally in ad* disks and another in da* disks which are firewire-connected. Without firewire disks mounted, reboot succeedes but with them it hangs.

If I remember correctly, this has appeared also with UFS-mounted firewire disks.
Make a zpool on fw disk or disks. Mount it. Try to reboot.
