I have two Rock Pi S boards. I am facing an issue of random system crashes. There doesn’t seem to be any particular trigger which causes crash.
- In official debian with 4.xx kernel the crash frequency is quite high. Crash happens almost every two-three days.
- In Armbian with 5.15 kernel (Image from github: Armbian_22.05.0-trunk_Rockpi-s_bullseye_current_5.15.32_minimal) , the crash frequency is considerably lower. It happens mostly after 15-20 days. But sometimes, it also happens just after a day.
I have tried following fixes without success:
- Changed power supplies. Both power supplies had 5v 2A and 5v 2.5A rating respectively
- Changed SD cards
- Checked with both boards
Main issue is when the crash happens, the kernel log is not preserved. Hence it is not possible to know the main cause.
