Ok, so I have the MP kernels built and (mostly) booting, but
I'm having some fairly random problems with them.  The
machine is a Dell Precision 420 dual PIII-1GHz; NetBSD
-current from 26 Oct with sommerfeld_i386mp_1 applied.

The machine spontaneously resets during strenuous work -
I've been using make release to test this; it usually goes
on cleandir in libc.  On one occasion it froze rather than
reset; unfortunately I was in X and couldn't tell if we'd
dropped into DDB.  I haven't managed to reproduce this.

This *does* seem to be related to the MP stuff rather than
-current; I haven't yet managed to make GENERIC or ANDUIN
(both built without the sommerfeld_i386mp_1 branch updated)
go down.

I've attached the GENERIC.MP dmesg output below (it usually
boots OK, although once or twice it's got stuck on clcs0.) I
did briefly manage to get the ANDUIN.MP kernel I mentioned
yesterday to boot, too; but currently it resets at the
"cpu1: CPU 1 running" line.

Any suggestions appreciated.
