My 2 NIC proxy arp firewall started spitting these out in 2.5..

Jul  9 22:17:52 equinox kernel: nf_hook: hook 0 already set.
Jul  9 22:17:52 equinox kernel: skb: pf=0 (unowned) dev=eth0 len=46

There's no real pattern that I can observe to trigger them, although...

(root@equinox:davej)# grep "hook 0 already set" /var/log/syslog.0 | wc  -l
   7660

It does seem to happen quite a lot in this particular setup.

        Dave
