I'm annoyed by the same problem, too.
My server is NetBSD/arm32 1.5S (CATS) and
NetBSD/hp300 1.5S and NetBSD/newsmips 1.5S hang
when they try to read files on the NFS server.
news68k, i386, pmax and macppc (they are also 1.5S) do not
have the problem, and 1.5.1_ALPHA i386 also hangs on access to
1.5S i386 server. Before upgrading server to 1.5S from 1.5,
there was no problem, so I guess it is not client problem.
According to tcpdump output, it seems that the server replies to
the clients' request, but clients do not response it at all.
