For example, I remember one very expensive test box was acting as an AP and it just ignored PM bit from the clients. No wonder the packet loss was high :) In this case it might that the way Veriwave behaves so which makes it easy to reproduce the bug. And that's a good thing. Any chance you could get full trace-cmd logs (ath10k, mac80211, cfg80211 and hostapd) when the bug fails with Veriwave? I'm sure that would get more hints what's happening. -- Kalle Valo _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
