...and the server? Something is preventing that RPC payload from being
delivered...

I can ssh to the server fine. The same server also serves my NFS home
directory to the box I'm writing this from and I've not seen any trouble
with this box at all, it's a 2.6.18-xen box.
If I downgrade the problematic box to 2.6.24 then the hangs do not
occur. They do occur with 2.6.25. (sorry that's a critical bit of
information which I stupidly forgot to mention up til now).
