what network card are you using? there is a subtle problem that high traffic (multiple flood-pings) causes with 3c509 and etherexpress's (someone posted a patch for the etherexpress driver) only under SMP. Can you try running the machine with a uniprocessor kernel?

(As it dies, loads are 80+.)
Are you sure it's the same way? Does the first computer die with a high load also?
