Subject: [2.6.23-rc3] NFSv4 client oops

While upgrading nfs-utils on my NFSv4 file server (F7 x86-64 
2.6.23-rc3), I got an oops on the NFSv4 client (FC6 x86-64 2.6.23-rc3), 
and communications stopped.

I rebooted the client, and everything was fine again.  Then, on the 
server, I removed an extra nfs-utils package left over from FC6, causing 
the nfs daemons to be restarted.  Another oops.

So it seems like whatever Fedora does during an nfs-utils upgrade __on 
the server__ is causing a remote oops __on the client__.

NFSv4 client kernel config also attached.

Never seen this problem before, but then again, never did a remote OS 
upgrade of the fileserver while running NFSv4 before.
