nfsd already wedged up and holds a lock, this is expected.


I'm not sure what you're doing here, but a viable work-around for now
might be to use nfsv2 mounts, something like

  mount -o vers=2 ...

or to keep v3 and disable readdirplus doing something like:

  mount -o vers=3,nordirplus ...

The later I didn't test but was suggested on #linuxfs.
