Specifically: * Without the patch and without nconnect, everything works on both 12.2 and 13.0. * Without the patch, with nconnect, and without delegations, everything works on 12.2, but on 13.0 clients lock up when they try file I/O. * Without the patch, with nconnect, and with delegations, clients lock up on both 12.2 and 13.0. * With the patch on 13.0, everything works even with nconnect and delegations.
