Hi Trond, Arnaldo, Al
	I tried reproducing using a local filesystem and couldn't 
(machine survived 3 make -j10 kernel compiles). Here is another oops for 
the collection. Al i'll remove you from further CCs now.

client: 2.5.27-serial, 3c905B
server: 2.4.19-pre5-ac3, 3c905B
connection: 100Mb/FD

I got this message before it oopsed;
RPC: garbage, exit EIO
