Do you have a little more detail than that, i.e. the panic message
itself? This problem is likely to have been fixed since 1.2, there
was an off by one error in nfsrv_readdir{plus}, which was fixed
in 1.2.1 already.

You can apply the following diff to your 1.2 source tree (though you
might need to remove the $NetBSD$ RCS ids from the diff for it to apply
cleanly).
