[1.] One line summary of the problem:    
Dual (2) AMD ATHLON MP 1900+ CPUs gives APIC error on CPU[0]: 00(02)

[2.] Full description of the problem/report:

Dual (2) AMD ATHLON MP 1900+ CPUs
ASUA7M266D Motherboard
2 sticks of  Corsair CM72SD512R-2100 (1Gb RAM)

When booting SMP-Kernels version 2.4.7, 2.4.9, 2.4.18 the box hangs with the
following error:

APIC error on CPU1: 00(02)
APIC error on CPU0: 00(02)

Durning the POST I get this, but do not know if it means anything.

CPU0 AMD ATHLONG (TM) MP 1900+
CPU1 *AMD ATHLONG (TM) MP 1900+

Not sure what the asterick means.

Complete message on the screen follows prior to lockup:

[7.7.] Other information that might be relevant to the problem
       (please look in /proc and include all information that you
       think to be relevant):

I ran memtester <http://www.qcc.sk.ca/~charlesc/software/memtester/> on the box
for 25 hours with no errors, so I pretty sure the problem is not with the RAM.

The box runs fine on a single CPU kernel. I swapped CPUs on the motherboard (to
test the other CPU), booted an SMP kernel and the box hung. 

Booted a single CPU kernel and the box works.

Swapped BOTH CPUs out with for new CPUs. Booted and SMP kernel. Box hangs.

Swapped out the motherboard. Tried both the new CPUs and the older CPUs and an
SMP kernel. Box hangs.
