I do have NFS mounts, but *NOT* through IPoIB. At least they *shouldn't* be.

I don't think that's the problem. If I had NFS mounts over IB, I should
get errors when I shutdown IB by itself with 'service openibd stop'
command.

I have no need for IPoIB at the moment. Is they're any way to confirm
it's not being used, or explicitly disable it.
