[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!
