I am not quite sure, what wifibox does, I didn't see a netif stop in the 
wifibox shellscript

What was happening: I booted the laptop, rtw89 didn't associate within 
30 seconds. (This happens sometimes, I don't know why).

Probably while I was firing up wifibox (/usr/local/etc/rc.d/wifibox 
onestart), the interface associated, and then the panic happend. (I 
actually managed to reproduce it once today)
