linux smp 2.2.17 hangs

[llorenc]

Hello. I'm new here. I have a problem with a dual processor motherboard
(Supermicro PIIIDR3) running linux smp 2.2.17. When I run two for loops,
(one in each processor) after a while my computer hangs. Can anyone help
me please?

Here are the code:
main()
{
unsigned int;
for(i=0;i<100000000;i++)
    ;
}

At the pronpt shell:
> gcc loop.c -o loop
>time ./loop & time ./loop
