On a RHEL7 kernel, sometimes the NFS client hangs during the boot when multiple NFSv4.1 mount entries are in /etc/fstab.

~]# cat /etc/fstab | grep mnt
192.168.122.10:/export1 /mnt1    nfs _netdev,hard,intr,noatime,vers=4.1,rsize=32768,wsize=32768 0 0
192.168.122.11:/export2 /mnt2    nfs _netdev,hard,intr,noatime,vers=4.1,rsize=32768,wsize=32768 0 0
