My Pi keeps locking up - cannot interact with it via keyboard (even Ctrl-Alt-PrintScr commands) or anything else. Screen (console) frozen.
Pulling power out and rebooting brings it up looking fine again, and there's nothing in syslog/
journalctl -k around the time of the crashes - it just plain freezes up.
It's been in use for 24 months or so and has been reliable up to now.
I did once catch a screenful of kernel death messages (usually there's nothing on screen to indicate a problem) - I can upload that if helpful.
- Pi 3b running raspbian 9.
- Has Gigabit USB ethernet adaptor (yes yes I know it's usb2 but it's still faster than 100MBs ethernet)
- Has external RAIDed drives via USB
- Has TV stick
- Runs samba, nginx, mysql, php 7.0 - sometimes heavy use, but it's not been under heavy use when it's died recently.
- official PSU
Anyone any ideas?
