Synopsis: [ath] [net80211] BAR TX overlapping with key renegotiation is causing issues? State-Changed-From-To: open->closed State-Changed-By: adrian State-Changed-When: Fri Oct 5 13:59:11 UTC 2012 State-Changed-Why: This turned out to be an invalid bug - the actual cause of my disconnects were "EAPOL frames were non-QoS and dumped into TID 16; then they'd be put in the same hardware TXQ as best effort traffic; any non-QoS broadcast/multicast traffic (eg ARP) would end up in TID 16." Then "if any powersave occured, the EAPOL frames may be stuck in a software queue; the ARP frames would be stuffed into the CABQ and the ARP frames would go out first. But if they came in AFTER the EAPOL frame, the EAPOL frame would have a sequence number which is earlier and it'd be dropped.." http://www.freebsd.org/cgi/query-pr.cgi?pr=171816
