I saw this from using CIFS, and I also saw a note about it in a Bugzilla entry 
saying that this was a debug message added by Arjan IIRC.  Therefore this is 
coming out of the particular kernel version you are using.  See if you can 
get an updated kernel from Arjan's place

http://people.redhat.com/arjanv/2.6/RPMS.kernel/

That may or may not help, but the main news is I don't think this is NFS 
specific.
