random lockups on new computers

I just purchased several new computers. 366 mhx Celerons with 32 mg ram and an
Intel ether express 10/100 card. I'm running the stock Red Hat 2.2.5-15 kernel
and I get randum lockups where all I can do is press the reset button. Below
is what I get if I run ksymoops -m /boot/System.map crash.msgs. I can't make
anything out of this. Any help would be appreciated. I've found that if I do
not load the network driver the computer seems to be stable. I'll need to do
more testing to be sure.

Options used: -V (default)
-o /lib/modules/2.2.5-15/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /boot/System.map (specified)
-c 1 (default)
