Network port of RPi3 just goes dead

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:
  • linux-raspberrypi 4.9.39-1
  • raspberrypi-bootloader 20170721-1
  • raspberrypi-bootloader-x 20170721-1
  • raspberrypi-firmware 20170721-1
  • systemd 233.75-3.1

Code: Select all

/etc/systemd/network/br0.netdev
[NetDev]
Name=br0
Kind=bridge

Code: Select all

/etc/systemd/network/br0.network
[Match]
Name=br0

Code: Select all

Have you tried testing with another distro to confirm that it is an issue with Arch and not a fault on the board itself?

There is a fix for a bridging issue in Raspbian (the brcmfmac driver AND the smsc95xx driver both had the same fault), not sure if it is also in Arch, that might be the problem. Think the fix in in kernel 4.12 and up. We backported it to earlier Raspbian versions.

Thanks for the reply... any additional info? Seems like systemd 233.75 was to blame; 234.11 hasn't choked since updating to it 7 days ago.
