For me, a couple other people over the last few weeks, and I know for JF002 also from that chat, the 5.9 kernel version of Armbian seems to work fine... I used the latest of them, Armbian_20.11.3 (ubuntu focal variant), and froze the kernel and firmware versions (an option in 'armbian-config') so that until I find out a fix, or find/hear of a later version working it won't update and break on me.
