I installed Armbian xenial 3.4.112 on an Orange Pi PC in July of 2016. It ran non-stop until sometime in February. I realized it was no longer sending data to the internet.
When I checked, the Orange Pi PC was still powered. However, the green+yellow ethernet LEDs were both blinking together at what looked like 2sec intervals.
After only a short time of running, the CPU was already 84C. When I originally had put the Orange Pi PC into service, it would remain close to 43C.
I connected a monitor and keyboard. It booted and a look at syslog showed the eth0 was looping on `DHCPDISCOVER`.
I tried `ifconfig etho down` and `ifconfig eth0 up` and not change.
I tried a new SD card with the latest download image Armbian Xenial 3.4.113. No change in behavior. The Orange Pi PC was running but the eth0 would not.
I replaced the Orange Pi PC with a new one and tested both the new SD image and the old SD image worked fine.
I put the new Orange Pi PC back into service. It lasted two months before the same result with the ethernet
Any ideas what I may be doing that is killing the boards? What should I monitor with the latest board? I still have the two failed boards. Is there anything I should look at on them?
