Some things to try:

1: Include `magic sysrq' support in the kernel and use ALT-SYSRQ-T and S
when it has locked up. If you get some traces then please feed them
into `ksymoops -m' and report back.

2: If the above doesn't work, add `nmi_watchdog=1' to the kernel boot
options. That may catch the lockup.

3: Replace the NIC with another eepro100. If the problem goes away then
chuck the old one.

4: Replace the NIC with one of a different type (ie: swap with the other
machine). If that fixes it we look at the ethernet driver. Otherwise
we look at, umm, the rest of the kernel.
