It works sometimes on the problem system, and it always (so far) works in our lab. We tried NFSv3 over IPv4, NFSv4 over IPv4, NFSv3 over IPv6 and NFSv4 over IPv6. We are using the standard 'mount' that comes with the OS (Fedora 14, in this case), but we are re-compiling the mount.nfs binary, so perhaps there is still some problem in how we compile it...
