Hi people,

this is something new I'm triggering with rc5 + tip/master while rc4 +
tip/master is fine. Any ideas?

No clue.  I don't see any netfilter changes between rc4 & rc5.
I just tried to set up a bridge on rc5 with call-iptables=1
and I see no such splat.

If I had to guess, it looks like this thing:

#ifdef HAVE_JUMP_LABEL
        static_key_slow_inc(&nf_hooks_needed[pf][reg->hooknum]);
#endif

Strange, these static keys have been there for years.
Any chance you could send your .config or bisect this?

Thanks.
