It might be me, but looking at those traces, aren't they triggered by: static int ieee80211_tx(struct net_device *dev, struct sk_buff *skb) { ... if (WARN_ON(queue >= ieee80211_num_regular_queues(&local->hw))) goto drop; ... } Which would suggest that when MAC80211_QOS is disabled, the skb_queue_mapping still returns something higher then 1.
