I'm getting started with embedded systems and have Ubuntu server installed on a Mini ITX board for portability. It has 4GB of RAM and a 1.1GHz Celeron chip. I've since found that it reboots randomly, but often within a consistent timeframe. Just look at these uptime records from uptimed.
I don't believe temperature to be an issue, as lm-sensors says the system is mostly 48C. I removed 1 RAM chip at a time but the problem persists. Additionally, I can't get into MemTest86 by booting Ubuntu or a live disk before the system reboots on its own.
I'm going to try keeping the system in the BIOS and see if it reboots. This might tell if the problem is Ubuntu based or something with hardware.
Code:
# Uptime | System Boot up
