This looks very, very similar to what I had once, on similar hardware 
(4x Xeon 7xxx, SuperMicro). I didn't find a solution and didn't bother 
since the box isn't intended for FreeBSD. I did find (by accident) a 
curious workaround: I booted Linux (I used Ubuntu 8.04 amd64 LiveCD - 
just to boot it, without installing), then rebooted and booted FreeBSD - 
worked every time, but it's obviously not a long-term solution. If you 
can also verify that this "solves" the problem, then someone might work 
with you to produce a patch.
