How to debug?
After running since August with no issues, my Helios4 has now crashed twice during past week: the OLED remains visible without being updated, the fan remains quiet (unlike after shutdown), all services are down. After unplugging & plugging the power the system starts & all services are OK, but obviously the logs are gone. After reboot log.hdd has very little, dmesg shows no errors.
How can I move logs to permanent storage or what can I do otherwise post mortem ... or is it the time to rebuild the system on a new SD card?
