NFS Client can't reconnect (RPC timeout) after reboot

[Aryeh Friedman]

I get a RPC time out when I attempt to reboot a 11-STABLE (1st uname) NFS
client attempting to connect to a 11-STABLE NFS server (2nd uname):  (Note:
NIS continues to work w/ "server" being the NIS server also note rebooting
the server clears it but restarting rpcbind/nfsd/mountd does not)
