Verrryy interesting. I thought it was just me, but I had to give up on
the newer NFS client and server for similar reasons. One thing that
_really_ triggered it was running a large patch on the client against
kernel source living on the server. Dozens of ".nfsd....." files would
appear (and stay) throughout the hierarchy. After all was done, and with
no errors reported by patch, a build would fail miserably. When I took a
closer look, many files which were reported as being patched had their
original contents!

Strange. I gave up the 2.1.x series and went back to 2.0.30 with the
original NFS support. No problems at all (except it's slow).
