A possibly related problem we've seen here: FreeBSD sometimes needs a hard reset (hit reset button) to reboot, while a software reboot will hang during bootup. This happens on FreeBSD boxes with 3.1R or 3.1-STABLE, onboard Adaptec 7890 U2W controller. Various (Seagate, IBM) LVD disks on LVD chain, *and* DAT on single-ended chain. Using verbose boot, we see that the hang occurs while probing the DAT and/or the CDROM player on the SE chain.
