kswapd is still dieing on boot with SMP enabled (and this time the second

Does this indicate something is wrong with SMP and the MM code, or that
some PPC-specific part needs fixing? I've tried to keep up on
linux-kernel, but it's a little overwhelming ;)

The SMP stuff in Linux/PPC currently only supports the Apple MP
architecture (I think they call it "powersurge").  Your MTX board
probably has entirely different ways of coordinating the CPUs.  Have
you looked at arch/ppc/kernel/smp.c?  I think that's where you'd have
to start changing things.

This is true, and I need to finish stuff in smp.c, but the same crash
occured from 2.2.0-pre5 on, without the second CPU being active. Patching
the kswapd portion of back to 2.2.0-pre4 fixed this.. Look for a message
in the archives from Ryan Nielson, I believe.

Can anyone verify 2.2.0-pre9 works on a SMP Pmac? (or for that matter,
vger.. if vger works I can figure out what changed)
