I just built a new image and the board works again - *thank you* I'll tie down the kernel package for now.

ok, I tried it with the official images (focal with 5.10 and buster with 4.4). Both start, but show kernel oops as soon as something is started there. Seems like the voltage regulator has some hardware problem. Yours, Alexander

Hello, it seems I got miss understood - my posting was not meant as a plea for support, more like "has anybody seen this already ?". I have not yet found the time to test the supported Armbian image yet, but will do so later today. Yours, Alexander

Hello, my renegade started failing about two weeks ago after a "apt update && apt -y upgrade". Symptoms are: slow network, shutdowns, kernel panics I tried to repair by installing a fresh kernel, compiled from the source, with no real improvement. So I resorted to creating a new SD card with a complete image (current, focal, server, minimal). This boots stable, but still shows issues. Find my "armbianmonitor -u" at http://ix.io/3rCS The only suspicious messages I can see in the logs are [ ] vdd_logic: Restricting voltage, 1175000-950000uV [ ] rk3328-dmc-freq dmc: Cannot set voltage 1175000 uV [ ] devfreq dmc: dvfs failed with (-22) error Is the board dying of age or is some software no longer working ? I'll try an official image next.
