This looks somewhat straight-forward to diagnose and debug. I don't however have any devices to reproduce this with. Would someone please describe -exactly- what device(s) I need to try and acquire to reproduce this behaviour? Or if you have it happening for you, would you please do a tcpdump on the wifi interface and capture all of the radio frames in question? I'd like to see how often it's sending power save mgmt frames. tcpdump -ni wlan0 -y IEEE802_11_RADIO captures the frames. Please take a snapshot: # tcpdump -s 0 -v -w pcap.out -ni wlan0 -y IEEE802_11_RADIO Thanks!
