FS#2001 - Asus RT-N56U: Connecting to 2.4 GHz WiFi may not work after reboot

Asus RT-N56U var A1.
OpenWrt 18.06.1, r7258-5eb055306f

Occassionally after re-boot, the radio0 (2.4 GHz) does not seem to be working properly - clients can see the AP but cannot connect repeatedly and fail with “Authentication error” - no station gets associated.

I found that repeated switching radio1 on/off may eventually show a stack trace in the log - then all of sudden radio0 (2.4 Ghz) starts to work.

At the moment, I keep radio1 in “monitor” mode with the lowest transmit power of 0 dBm. If there is a crash in the log after reboot, then radio0 works. If not, then it does not work.

The log is attached. The stack trace happens at 19:10:32, which got triggered by

root@OpenWrt:~# uci del wireless.default_radio1.disabled='1'
root@OpenWrt:~# uci commit
root@OpenWrt:~# service network restart

at 19:10:21.
