The board also has a wifi device, but that device's driver is affected by https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720580, so I had to blacklist r8723bs to stop systemd from spending 100% CPU journaling constant complaints from it. So the Ethernet device is the only working network adapter. Merely rebooting the system didn't fix anything; I had to shut down and actually power cycle the board to get networking to come back. If this keeps happening, it will make the machine useless for its intended use case as a low power server. It looks like the driver must have somehow gotten the device into a very bad state?

The board also has a wifi device, but that device's driver is affected by https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1720580, so I had to blacklist r8723bs to stop systemd from spending 100% CPU journaling constant complaints from it. So the Ethernet device is the only working network adapter. Merely rebooting the system didn't fix anything; I had to shut down and actually power cycle the board to get networking to come back. If this keeps happening, it will make the machine useless for its intended use case as a low power server. It looks like the driver must have somehow gotten the device into a very bad state?
