After upgrading, I noticed messages like these appearing during rebooting, immediately after kernel: NFS access cache time=60
kernel: rpc.umntall: 10.1.1.102: MOUNTPROG: RPC: Port mapper failure - RPC: Timed out sometimes it appears twice, once it appeared five times. The system eventually completes booting and there are no more messages like this. /etc/fstab has the following 10.1.1.102:/usr/src /usr/src nfs rw,readahead=16,late 0 0 Logging in, the nfs share is mounted normally. --
