Network port of RPi3 just goes dead
Posted: Sun Jul 23, 2017 12:37 pm
For no reason that I can determine, my RPi3 experiences network failures at random times. It is running Arch ARM and the linux-raspberrypi kernel (4.9.39 currently). Symptoms include no lights on the onboard LAN (no yellow and no green). The only way to recover is a manual power cycle. I found a similar report from another user experiencing this same issue that makes me think it's not just me. That user is not using a bridge network, he is using a simple DHCP profile so that makes me think the bridge in my setup is not to blame.
Details:
Distro: Arch ARM (armv7l not aarch64)
Hardware: RPi3
What's connected, truly headless: only power and LAN. No HDMI, no USB devices.
How the LAN is managed: systemd-networkd with bridge using the below settings.
Key software versions:
