I think it's more likely the power supply went bad than the Pi. Can you borrow an official Pi 4B wall wart from someone for testing purposes?Hi, I have a 4B (2GB) which was been running for almost two years without issue, some reinstalls but everything kept mostly the same running adguard home or pihole. Recently adguard wasn't resolving and I checked the hdmi output after ssh wouldn't work and found the screen was just fuzzy coloured lines.
The message at the start of the kernel panic ranged from "Unable to handle kernel paging at virtual address ffffffc008934578" and "Internal error: Oops - undefined instruction 0000000002000000 [#1] PREEMPT SMP"
Since then I have tried multiple SD cards, power supplies and OSes, was running dietpi and went back to raspberry pi os lite, updating eeprom, made sure the OSes were updated fully, tried not updating the OS from the install images, ran memtester and didn't fail for 1G 5 runs. This morning I was sitting there waiting for it to crash and after running apt update it kernel panicked saying something like "undefined instruction" possible but definitely said "PREEMPT SMP". It now is not booting again with 8 flashes of the green LED. What is can I do now? (It was not overclocked either).
