Sorry for not being clear: the client is running 2.6.37-rc1.   The
server is running RHEL 5.5.

There are no unusual messages on the client... but I just logged into
the server and I see lots of messages of the following form:

  nfsd: request from insecure port (192.168.8.199:35766)!
  nfsd: request from insecure port (192.168.8.199:35766)!
  nfsd: request from insecure port (192.168.8.199:35766)!
  nfsd: request from insecure port (192.168.8.199:35766)!
  nfsd: request from insecure port (192.168.8.199:35766)!

(192.168.8.199 is the address of the failing client).  I can only assume
that these are a result of my recent issues, since I don't have access
to the system log (with timestamps) on that machine.
