This was not an NFS problem--it's an amd problem.  I had no problems manually
mounting the file systems.  amdcomplains about "bad address" when it
attempts to mount.  The amd that comes with 2.2.1-RELEASE works fine
(on both 2.2.1 and 2.2.2).

I believe youu're describing the infamous packet overrun problem.  Check the
handbook under "Advanced networking".
