If these are the same blades as the Intel SBX82 blades, then the code 
that drains the keyboard interface at boot time will cause the system to 
hang if the ps/2 keyboard (atkbdc?) isn't disabled.  Devon H. O'Dell 
just sent me a list of his PRs yesterday (via the freebsd-amd64 list) 
that resolve this problem and several others:

    I've implemented a fix for this utilizing ACPI reboots. Please
    apply kern/94939 and tell me if shutdown(8) with -r or
    reboot(8) works for you. My suspicion is that it will.

    Also, you may be interested in kern/94822, as FreeBSD won't
    hang on start-up attaching atkbd(4). If you're working on
    Intel SBX82 blades, specifically, kern/94833 and bin/94815 may
    also be interesting to you.

Maybe these would be helpful for you, also.
