The misbehaving device in this case is the board's integrated
Ethernet, which appears as a USB device. 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?
