I'd suggest sending this e-mail to freebsd-net; there have been significant link layer changes in 8.0, and it's possible this is a side effect (and bug) from that. The appropriate people will pick it up on that list. Also, I notice you're running 8.0-RELEASE, rather than the latest patch level (which included some important security impovements and stability improvements); you may want to slide forward using freebsd-update or a manual rebuild. You will need to reboot to pick up some of the improvements.
