Firstly, thanks again for taking a look at this, still doesn't work
though =(

I grabbed the newer versions from these files and stuck them in my
source tree, recompiled and it still panics - so I'm back to a non-smp
kernel again.

Just to check the versions.

steve@moose 5 0 % fgrep "\$FreeBSD" /sys/i386/include/smp.h /sys/i386/i386/mp_machdep.c /sys/i386/i386/mpapic.c    ~/  3:26pm
/sys/i386/include/smp.h: * $FreeBSD: src/sys/i386/include/smp.h,v 1.53 2000/08/06 00:04:02 tegge Exp $
/sys/i386/i386/mp_machdep.c: * $FreeBSD: src/sys/i386/i386/mp_machdep.c,v 1.118 2000/08/06 00:04:02 tegge Exp $
/sys/i386/i386/mpapic.c: * $FreeBSD: src/sys/i386/i386/mpapic.c,v 1.40 2000/08/06 00:04:03 tegge Exp $

I've just copied the smp.h into /usr/include/machine as well, but now I can't seem to
build anything at all, so it's possible I screwed up somewhere (although the newer
panic below does indicate I managed to build a kernel with the new versions at
least because the Changing APIC ID line only appears in the newer files I think..)

=-= Panic Information :

Changing APIC ID for IO APIC #0 from 0 to 16 on chip
panic: can't control IO APIC #0 ID, reg: 0x00000000
mp_lock = 0000000a; cpuid = 0; lapic.id = 01000000
Uptime: 0s

[ Machine freezed ]

Anyway, I'm just about to cvsup down a completely clean source tree. Any ideas
which I should go for - i.e. which might give me working SMP ? 

So... which should I try: HEAD, RELENG_4 (again) or wherever RELENG_3 is now ?

[I'm open to all ideas on this one, as I find using one CPU on this box for
what I need to do a little too slow for most things.]

Tia,

	Steve
