[issue1695] NFS-related system breakdown

If I do NFSv3 UDP it works fine. I copied the file 5x with no b/lock failure. I
then remounted it as NFSv3 TCP and it failed as yesterday. I killed X and looked
at dmesg. I now saw some new messages:

EXDEV case 1 0xd1b06a88
EXDEV case 1 0xd1b06a88
EXDEV case 1 0xd1b06a88
EXDEV case 1 0xd1b06a88
[diagnostic] cache_lock: blocked on $addr ""
[diagnostic] cache_lock: blocked on $addr ""

Oh, and yes -i(ntr) did the trick. I was able to ^C the cp(1) and restore normal
operation.

What's next? tcpdump on the server side ?
