Was the laptop attempting a udp or tcp connection? I seem to remember a while 
back needing to switch to tcp for everything so that nfs was stable. On a 
very similar system with very few connections, udp still functions fine.

No-one else was having a problem so I didn't probe any further. It also wasn't 
the easiest thing to replicate, for me at least. I've also had other 
instances where nfs will kill a system, so I've avoided using it in the hope 
that eventually other people would be interested enough in the problems/bugs 
that exist and then maybe I can assist ...
