It seems to me that if we want to find out what happens when the "green LED of death" appears, then we need to provide more technical information.
For example, the following questions immediately arise.
1. Which memory card was used (and even on which card reader the image is recorded).
SanDisk Ultra 32GB A1
2. Which case was used (closed, open, metal, plastic, and so on.
3. What kind of power supply. Whether there was a voltage drop or frequent malfunctions in the electrical home network.
Original power supply
4. Whether the temperature of Raspberry was controlled (for example, I have constant temperature control turned on and when I reach 60 degrees, Raspberry is turned off).
Cooler running non stop.
5. Are any devices connected to the GPIO
No devices were connected to GPIO. Only the cooler was connected to 5V.
6. Where is Raspberry physically located and can it be that the microcomputer is exposed to humid air or is in a stuffy shoe box =)
Office space 25C
7. In what mode was the computer used? Constantly worked or often turned on and off.
Headless with no X. K8S was running but without any pods.
What programs were most often used (server or web browsing through Chromium and so on)
Have any changes been made to config.txt
Indicate the firmware version and whether EEPROM was tried to flash (before or after the "green death LED").
Stock EEPROM, no changes in config.txt were made.
8. How the computer behaves after the appearance of the "green death LED". How much current does Raspberry consume in this case (measure the current with an ammeter). Can check some signals on the board with an oscilloscope? What happens if you lower the voltage from the power supply to Raspberry (for example, to 4.8 Volts or lower, to 4.5 Volts. Will the red light disappear?).
9. Perhaps it makes sense to post photographs of Raspberry and setup, the environment in which the microcomputer worked. That is, indicate the brand of keyboard, mouse, connected devices.
Only the ETH was connected, not WiFi or keyboard, mouse was used.
