The problem is that the kernel ran out of resources for network buffers
(the panic may be related but in any cases it's, wrong :)
The problem may be that your network driver pre-allocates too much resources.
A workaround has been commited but is not in 1.4.1. You may want to upgrade
your kernel with the sources from the release branch (available either from
sup or anoncvs, I'm pretty sure all the infos are on the www site).
