The problem is reproducible fine: I'm running in a loop SCP traffic up and down to my ISP host; when the background scan every five minutes takes place the traffic gets STALLED and IP comes not to work again: Nov 23 17:13:33 unixarea dhclient: New Broadcast Address (wlan0): 192.168.2.255 Nov 23 17:13:33 unixarea dhclient: New Routers (wlan0): 192.168.2.1 Nov 23 17:18:33 unixarea kernel: wlan0: ieee80211_bg_scan: active scan, ticks 36537257 duration 150 Nov 23 17:18:33 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode on Nov 23 17:18:33 unixarea kernel: wlan0: scan_task: chan 7g -> 1g [active, dwell min 20ms max 150ms] Nov 23 17:18:33 unixarea kernel: wlan0: scan_task: stopped, [ticks 36537415, dwell min 20 scanend 36537408] from now the interface does not let pass frames anymore Nov 23 17:18:33 unixarea kernel: wlan0: ieee80211_sta_tim_notify: TIM=1 Nov 23 17:18:34 unixarea last message repeated 3 times Nov 23 17:18:34 unixarea kernel: wlan0: [00:13:f7:0d:08:48] save frame with age 40, 1 now queued Nov 23 17:18:34 unixarea kernel: wlan0: [00:13:f7:0d:08:48] save frame with age 0, 2 now queued Nov 23 17:18:34 unixarea kernel: wlan0: ieee80211_sta_tim_notify: TIM=1 Nov 23 17:18:35 unixarea last message repeated 14 times Nov 23 17:18:35 unixarea kernel: wlan0: [00:13:f7:0d:08:48] save frame with age 0, 3 now queued Nov 23 17:18:35 unixarea kernel: wlan0: ieee80211_sta_tim_notify: TIM=1 ... I tested the same in an older 10-ALPHA4 laptop (running r255948 from October 2013) with the same physical WLAN card; there is no problem with the bg scans every 5 minutes, it just goes ahead after any scan; this is an issue in head. matthias -- Matthias Apitz, guru@unixarea.de, http://www.unixarea.de/ +49-170-4527211 1989-2014: The Wall was torn down so that we go to war together again.
