I'm experiencing a strange problem of OpenWrt router randomly restarting, especially when there's a USB device plugged in. Are there any crash logs in OpenWrt that I can inspect? What could be the possible troubleshooting/investigating steps?
There are no visible errors or alerts in the boot log. it sits idle, and suddenly trips.
BusyBox v1.30.1 () built-in shell (ash)
