Hi,
I found one of my PC Engines APU3 in kernel panic. What changed recently
on this machine, I started node.js on it about two days ago.
- it runs local installation of Zigbee2MQTT
- nodejs / Zigbee2MQTT opens /dev/cuaU0
- cuaU0 is ITEAD SONOFF Zigbee 3.0 USB Dongle Plus V2
This is very new workload on this machine. Before I never had kernel
panics on it, but that machine was never really busy with anything as
it's mainly for experiments.
I have it in the ddb prompt, if anyone would be intrested to see
something more there. I will reboot probably tomorrow or so...
...
starting local daemons: cron.
