I got a little further with the lock up problem, and it is related to MPS reporting a 2nd processor being present in some PPro systems when in fact only one CPU is really installed (but MPS is reporting default table entry 6 with a second CPU as present). What seems to be different here is that on this system, NT and NetWare both timeout on attempts to activate the non-existent CPU, while 2.4 hard hangs after sending a STARTUP_IPI command. hpa does some work on the APIC code I've noticed, so I thought I'd ask him about it.
