Thanks for the logs! I would've loved to get full traces or debugs with dumps though (I can't see anything related to SWBA in the logs). Anyway - it seems that device crashes after ~5 beacon intervals. Can you confirm (with another device/sniffer) whether the ath10k AP sends any beacons on the air before crashing, please? Did the card ever work with any previous OpenWRT version?
