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.
