This one can happen if the NAT module is loaded after ip_conntrack and
there are already existing conntrack entries, but it should be harmless.

This one probably results from the above, when the conntrack is altered
it may end up in a different hash bucket, LIST_DELETE complains if it
doesn't find it on the list where it is to be removed from. Hmm .. so
the above is probably not harmless after all, when freeing the conntrack
we don't remove it from the list if netfilter debugging is enabled.
Does disabling CONFIG_NETFILTER_DEBUG make any difference?
