Hmm, the causation may be going the other way -- if the disk is
generating too many IRQs for the CPU to handle, then network packets
might get dropped.  Alternately, perhaps the PCI bus is maxed out?
Anyway, this sounds like a problem local to the client.  Is there a
way to slow down the disk IO so that it doesn't wedge the machine?
