SMP Athlon troubles under high load

[1.] One line summary of the problem:
hangs on dual athlon system under heavy load.

[2.] Full description of the problem/report:
The systems hangs only under heavy load or during shutdown. It still happens appending noapic and mem=nopentium, removing the networking card or the ati graphic card. Although i can't remove the Adaptec 2100s RAID in order to boot. The system works fine compiled with only one CPU support. The temperature seems fine around 55C.

[3.] Keywords (i.e., modules, networking, kernel):
with or without networking and with or without modules.

[4.] Kernel version (from /proc/version):
Linux version 2.4.19 (pau@lorien) (gcc version 2.95.4 20011002 (Debian prerelease)) #6 SMP It still happens under SuSE 7.3, 7.2 and 8 kernels. (2.4.16 and 2.4.18)

[6.] A small shell script or example program which triggers the problem (if possible)

I'm only able fastly hang the machine using something like this:
#!/usr/bin/perl
my $a = 0;
while ($a == 0) {rand();}

It usualy returns a Segmentation Faults and the machine hangs in a few seconds.
It can become freeze during the perl script too. The script can run during 10 seconds to 30 minutes.

The system hangs both 1.1 and 1.4 SMP specification and with or without using MP interrupts table.
MainBoard: Tyan 2460 with registered ECC memory.

The MB can't reboot normaly, but i think it is a BIOS issue, i should update it.

Good luck!

According to my notes, 644 isn't a valid CPU for reliable MP operation. The earliest Athlon rated 'smp safe' is model 6 stepping 0. Anyone with anything earlier that isn't having problems is getting 'lucky'.
