Reboot loop

[fm-maniac]

After around 2years of flawwlwss operation my system recently started to get caught in reboot loops from time to time. I've to do a manual reboot to get it up again. Until it stucks again. Does anyone has an idea what the root cuase might be? Maybe a worn out SD-card?

A snippet of the log-file posted below!

Yes, the SD-Card would me my first check.
Maybe also the ESP got bad, keep in mind that they mostly are cheap Chinese stuff.
It also could be the power supply going bad.
