>How-To-Repeat:
Boot the system... :-)
>Fix:
Unknown.  UP kernel runs correctly on the machine.
Only difference between UP and SMP:

  options               "VM86"
+ options               SMP             # Symmetric MultiProcessor Kernel
+ options               APIC_IO         # Symmetric (APIC) I/O
+ options               NCPU=4
+ options               NBUS=6
+ options               NAPIC=2
+ options               NINTR=48

Non-defaults due to specific prior panics instructing
such changes.
