If the systems boots okay from a hard reset, but (sometimes) hangs when booted with "shutdown -r", you've hit a known problem. There's been quite a bit of discussion about this on the freebsd-scsi list; search for "Boot-time scsi probe problem" in the list archives. A possible patch has been published.

Tor Egge came up with a work-around that seems to solve the problem most of the time. It isn't a fix. As far as I know, Justin has not heard back from Adaptec yet. Justin said that he is planning on checking in Tor's work-around until he can get a real fix. He said he would try to check it in later on tonight, but that may or may not happen, since he is busy. > i have several machines i can use for testing. so far i've twiddled > with timings and stuff, the code is from last week, but as far as i > can tell (i read "all" the major lists including cvs-all) nothing > has been committed into the tree... Well, here's Tor's patch. I don't think he'll mind if I give it out: http://www.FreeBSD.ORG/~ken/tor.adaptec_patch.031799 I upgraded a number of machines this weekend, and I had the same hang problem on a system with an onboard 7890. I fixed it with the above patch. Send some mail to the list once you try the patch and let people know whether it works for you or not.
