I just updated 2 of my systems to FreeBSD ???.net 8.2-STABLE FreeBSD 8.2-STABLE #2 r219138: Tue Mar 1 13:42:29 EST 2011 root@???.net:/usr/obj/usr/src/sys/SERENITY amd64 from 8-stable sometime around 8 release and just had to have the datacenter hit the reset button to bring the machine back. I'm reluctant to take this machine to current but if that fixes the problem I can do it. The other option is calling the data center and having them change the BIOS settings for me but that is also something I would rather not do. Thanks, Jonathan
