It's been mentioned on linux-kernel - a network layer change in 1.3.58 or so - there's a patch to xntpd to fix it (it has to do with bind on INADDR_ANY,port succeeding and getting traffic from a previous bind on localaddr,port... the kernel fix closes a potential security hole, but xntpd already compensated for it and now fails. I don't have the actual patch handy, sorry...
