Problem still occuring, found syslog entries of:

I was having lots of trouble with NFS when it was being carried over a
wireless link (a wireless bridge between my upstairs and downstairs). I
was getting the same errors you're getting.
I fixed it by using NFS over tcp - it defaults to UDP. If you add the
"tcp" option to the mount options, it will use TCP. You may want to give
that a try.
