I've got the same problem with FreeBSD 8 STABLE on athlonx-xp 2500+, 
motherboard Abit NF7-S, 2GB ram, 1Gb swap, ZFS.
I tried with custom and generic kernel, but the situation doesn't change.
I tried running in virtual machine a windows guest and a freebsd guest. No 
difference: the system reboot automatically after few seconds
