Thanks for the input, I'll pass it to the list.

Most of these Athlon victims are UP users, in fact, I
believe they are exclusively UP. Does MPS 1.1/1.4 play a role
in a UP system ever? I dont think the NForce2 chipset,
where we are seeing these hard hangs (no ping, no screen,
no blinking cursor, no toggling the caps lock, nothing) is
capable of SMP operation.

Now whats interesting is you finger the IDE as a potential
culprit and think its very low level. Interesting.

By the way, I've had trouble with SMP on a Tyan board with an
i840 chipset with Linux before - I was never able to resolve
the issue and had to return the board.

I've beaten on an Intel SR1300 and SR2300 dual Xeon (aka
Micron's Netframe 1610/2610 aka Sun 60x / 65x) and never run
into these hangs with kernels up to 2.4.22. The motherboard
is an Intel SE7501WV2 .

I have almost everything disabled and the error occurs.

Thats it. And this think locks anytime APIC is enabled. Its just a
matter of time.
