Message-ID: <576192B2.3000304@candelatech.com> (sfid-20160615_193933_002635_D0454F8B) Date: Wed, 15 Jun 2016 10:38:58 -0700 MIME-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Sender: linux-wireless-owner@vger.kernel.org List-ID: On 4.4.11 + local hacks, including fairly extensive pktgen changes.... When I overdrive transmit on a station with pktgen, I see this splat hit below repeatedly. Any ideas on what kinds of things might cause this? while (!skb_queue_empty(&local->pending[i])) { struct sk_buff *skb = __skb_dequeue(&local->pending[i]); struct ieee80211_tx_info *info = IEEE80211_SKB_CB(skb); if (WARN_ON(!info->control.vif)) { ieee80211_free_txskb(&local->hw, skb); continue; } Thanks, Ben -- Ben Greear Candela Technologies Inc http://www.candelatech.com
