SMP lockup with 2.4.12 on VIA chipset (still does it) (fwd)

[PinkFreud]

So far, I've received a few suggestions (and a patch) for the below
problem, but none seem to work, so far :(.  I thank the people who have
tried, though.

There has to be a way to track this problem down, as difficult as it seems
to be.

Is there any specific information which I can provide?  *Something* I
haven't tried yet?  I'm pretty sure that this isn't a hardware problem,
because this system is perfectly stable with SMP under 2.2.19.

Or should we just declare SMP as only working with *some* configurations,
and not others (despite it working in an earlier series, no less)?

*PLEASE* CC: me in any replies, I am not subscribed to this list.  Thanks.

Ok, all.  I finally got some time (and a null modem cable) to look at this
lockup a bit more.  To refresh everyone's memory, this is a dual CPU PIII
on a VIA chipset with a Matrox G400.  If I start X, switch to a text
console, and switch back to X, there's a 99% chance the box will lock up -
no keyboard, mouse, or network.  (This was brought up two months ago in
the 'Are we going too fast?' thread.)

Included at the bottom of this message are the kernel messages upon
boot.  NMI watchdog reported absolutely NOTHING when the lockup
occured.  Note that these messages are from the boot after the crash -
you'll notice that NMI watchdog is now reporting it's stuck on CPU#0.  In
the first boot (before the lockup), NMI watchdog seemed to be fine:
testing NMI watchdog ... OK.     

Please note that this lockup does *NOT* happen with 2.2.19 with SMP, nor
does it happen with 2.4.x WITHOUT SMP.  Therefore, I would think
whatever's causing this has to do with something that changed in SMP
between 2.2.x and 2.4.x.  Please feel free to yell at me if I should post
this elsewhere.

Without further ado, I present eriador's boot messages:
