[SOLVED][Odroid C2] Wifi AR9271 causes kernel crash after upgrade

February 13, 20206 yr

Hello,

I am using up to date Armbian Buster.

TP-Link TL-WN722N V1 USB WiFi dongle causes system crashes after kernel upgrade to 5.4.12-meson64 #19.11.8 SMP PREEMPT Thu Jan 16 20:12:23 CET 2020 aarch64 GNU/Linux.
Before updating the kernel, I had no such problem.
