Yes - but it was also giving different error message - which even not loaded ftp conntrack module. Basically it has been fine until conntrack started to use rcu. From that moment various errors started to appear with slub and some kernel debugging options - slab was fine. With your recent patch it's the first time I do not see oops with nf after 2.6.29 kernel.
