Hi,
I'm using WiFi hotspot (hostapd) on Dragonboard 845c
(sdm845|ath10k|wcn3990) running AOSP, and I run into following
non-fatal warnings when a station disassociates from the AP. I wanted
to raise the issue in case anyone had ideas what might be going wrong.
Any known issues? I can reproduce similar warnings all the way to
v5.15.y (or may be older LTS versions as well but didn't try yet).
