I just received four such servers, all intended for FreeBSD.... And  
I'm seeing exactly the same problem. I'm going to try booting Linux  
and then back into FreeBSD, but it's obviously not a solution. Anyone  
who might want to work on this can have a box like this to work on via  
remote KVM (including remote boot media capability) any time.

I'm going to go poke the supplier and Supermicro for some updated  
firmware.
Any progress on your end?

Some additional info: Safe mode boot gets a bit further, to the point  
where it tries to mount/read from /dev/md0, but then hangs hard.
