Spurious error messages in 2.4.19-pre6

[Richard Gooch]

  Hi, all. I've just upgraded a router to 2.4.19-pre6, and I'm now
getting these (presumably spurious) messages:
nf_hook: hook 0 already set.
skb: pf=0 (unowned) dev=eth1 len=46

Known bug?

                                Regards,

                                        Richard....
