I managed to look at messages from another machine running Linux and
it is using APIC ID 6, so the BIOS is ok. It may be that it doesn't
like the sequence of IPI's that we send. Although, we use the exact
method recommended by the MP spec. Look in start_ap() and try
disabling the second startup IPI (just use #if 0) to see if it works
