ipt_register_table() does get_cpu() then calls translate_table(), and
somewhere under translate_table() we do something which sleeps, only I'm not
sure what it is - netfilter likes to hide things in unexpected places.
I'll investigate this. the get_cpu() scheme was introduced as a fix for
a different (less serious) problem.
You'll get a reply until later today.

Fragmentation is like classful addressing -- an interesting early
architectural error that shows how much experimentation was going
on while IP was being designed.-- Paul Vixie
