nfsclient process stucks in nfsaio [SOLVED]

[Rong-En Fan]

Hi all,

I believe that this behavior is caused by the ``intr'' (-i) option to
mount_nfs(8). As noted by Stephan Uphoff in PR/79700, he does
not recommend use intr option. After remove the option, the dd
works well.

Sorry for the noisy :-)

However, I think some warnings can be added to mount_nfs(8)
about the usage of intr and its consequence. So this won't be
happened again.
