I am not smart enough to know exactly what is wrong with the diff but reverting back to revision 1.385.2.25 of /sys/i386/i386/machdep.c fixes the problem. Apparently, the problem is BIOS specific so that explains why I only saw it on one of my machines (the oldest) and not the others. This would also explain why other people have not seen the problem. At this point I would say that the problem really has nothing to do with SMP, it just so happened that I experienced the problem on an SMP machine.
