Another of mine just died. I had successfully flashed the v1.1 installer (and an imagebuilder snapshot build from the same time) back in February, and rebooted about 5 times since then (usually due to a power outage or similar). This morning, after a power failure, it failed to boot.
I have ordered the wires needed for the UART connection (my existing connectors were too large), and will attempt to recover that one tomorrow (I'll do the second one -- which bricked while flashing the v1.1 installer as mentioned earlier -- later, as I don't currently have physical access to it).
I'm wondering if I should maybe restore it to the pre-v1.1 layout given that the routers had been running and rebooting without issue for over a year before the v1.1 installer, and two have presumably OKD'd within a few months after.
