Are there by chance bugzilla entries for those? Just out of curiosity - NFSV4 is an area of interest to us, in the future.
Have you checked the newest kernel from the last few days? It has a few nfs fixes included:

I see NFS4 geeting used more and more, but still many production sites staying on NFSv3.
