Firstly, due to licensing issues, we have ceased maintenance and support for the Ubuntu system, making it impossible for us to further investigate many of the problems.
The issue where the system fails to boot after running for a period of time can typically be resolved by re-flashing the system. This is generally unrelated to kernel configuration, as most kernel configuration errors would trigger a failure on the very first boot. I suspect that a particular service or application may be enabled, causing the Ubuntu system's storage usage to continuously increase over time — for example, due to constantly generated log files. After running for an extended period, the storage space may become full, leading to the boot failure. I recommend using the journalctl tool to investigate this issue.
