Similar issue, crashes any time any Mediatek based client connects to the 2.4GHz radio. It's fine with ESP8266s, my laptop, my Qualcomm based 'phone.

BT Home Hub 5A (Lantiq XRX200) and a Plusnet Hub One, same device for all intents and purposes. Both act exactly the same. LEDE built from r3315, no local changes. Backing out https://github.com/lede-project/source/commit/71e86199ff192538ce9fde59e563e7f54ce9f99a fixes the hardlock, but it also stops the DSL daemon starting.
