If I have an NFS4 server successfully sharing a directory with a client and
both machines have valid IPv4 and IPv6 addresses should it be possible to
mount the directory using either IPv4 or IPv6?
Both machines are running 2.6.34-rc6 kernels, nfs-utils-1.2.2,
libtirpc-0.2.0 and rpcbind-0.2.0. Mounting over IPv4 works perfectly, but
IPv6 just times out while trying to mount the share. Using tcpdump I see
that the two machines exchange 40 packets before the client finally gives
up. There are no messages generated in the system log or dmesg of either
machine.

Yes, that should work if nfs-utils-1.2.2 is built with --enable-tirpc
and --enable-ipv6.

Are the IPv6 addresses correctly registered with DNS? Have you tried
"mount.nfs4 ... -v" ? Or:
$ sudo rpcdebug -m nfs -s mount
will produce more syslogging.
