Hello,
I've made some more testing, and noticed that device does not go completely
silent...
I can now reproduce this hang without large transfers with 'ifconfig wlan0 up;
iw dev wlan0 scan & sleep 0.02; ifconfig wlan0 down'.
The large tranfers caused connection to fail sometimes, leading wpa_supplicant
to issue scan that is aborted. Manually aborting scan causes device/driver go
into this partial silence state too (with beacons/probe requests received).
So maybe driver does not do all the required clean-ups for aborted scans?
Have you tested 'ifconfig wlan0 up & sleep 0.02; ifconfig wlan0 down'? Is the
scan part absolutely necessary?
