I was just playing with my new proxmox node. It is still imcomplete and still in the testing phase.
While trying by to find the wake-on-lan setting on the Supermicro X9DRH-IF board, I accidentally turned on the watchdog setting. For whatever reason, it causes proxmox to reboot a few minutes after bootup.
It got me pulling my imaginary hair before I figured it out. If i remember correctly, there was a saying that goes something like change only one thing at a time’.
