That is just a wild guess, but NFS mounting would happen always at the same stage of the boot, so maybe with the same source port number and you could be facing the problem that the connection is waiting for termination on the server (close_wait or fin_wait or something)... Se source port in working example is 798 and source port in failing example is 799 certainly not random. Olivier
