Funny you should mention timing... right now, the server does not show the runaway kworker. nfds faithfully spits out a few debug messages per second, but acts normally otherwise. I have put the server back in production, see if I can catch the runaway kworker when I have more users -- I'll get some flak if nfsd hangs again, but that's life. I am also setting up another, similar NFS server for testing purposes. Will report once I have more information.
