It boots fine if no network cables are plugged in (and in the test evironment on a quient lan). It's an SMP machine. My guess (from the panic message below) is that an arp query arives on an interface it's in the middle of creating or something like that (highly unsophisticated debugging conjecture). In the mean time I'm going to try a UP kernel and see if that masks the problem.
