FreeBSD 3.0-RELEASE #10: Thu Dec 10 17:45:28 PST 1998
root@hozameen.cs.ubc.ca:/usr/src/sys/compile/HOZAMEEN-SMP
(NOTE: from 'strings /kernel'; kernel doesn't boot so can't do uname)
>Description:
HP Vectra XU 6/200 dual 200MHz PPro ran SMP in several v.3 snapshots
(e.g. 3.0-980107-SNAP) but hangs early in boot process with 3.0-RELEASE
kernel.  Due to early demise I haven't been able to log the bootup info
or recover it via dmesg; however, last screen displays:

ISA Pin=1, IRQ=-1, Pol=0, Trig=0
IOAPIC #0 intpint 1 -> irq -1
ISA Pin=2 IRQ=-1, Pol=0, Trig=0
IOAPIC #0 intpint 2 -> irq -1
..........
ISA Pin=15 IRQ=-1, Pol=0, Trig=0
IOAPIC #0 intpint 15 -> irq -1

Debugging message inserted in /usr/src/sys/i386/i386/mp_machdep.c just
before
  CHECK_INIT(99); /* setup checkpoints */
(approx. line 1860) prints out but none of the subsequent trace or panic
messages in the code are seen.
>How-To-Repeat:
Make kernel with:
  options SMP
  options APIC_IO
and run on dual-PPro Vectra XU 6/200.  May be related to bug report
kern/8456 (SMP boot failure on dual PPro Everex PO-6200 with
3.0-RELEASE).
>Fix:
Fix not yet determined.  There have been MANY changes and additions to
interrupt setup code in 3.0-RELEASE re. 3.0-980107-SNAP, as well as the
apparent removal of special handling for CPUCLASS_686 (in
/usr/src/sys/i386/i386/mp_machdep.c).  Possibly there are motherboard
issues but it DID work fine in earlier pre-RELEASE snapshots....
