Public bug reported:
During the upgrade of a container from xenial to bionic, the container
stopped working after the reboot.
In an manual attempt to start the container:
# lxc start juju-3fae13-25-lxd-6
error: Monitor is hung
There are no failures reported in lxd/lxc related log files
The dmesg does give some possibly related lines:
[24085329.749762] unregister_netdevice: waiting for eth2 to become free. Usage
count = 1

[24085370.329020] unregister_netdevice: waiting for eth2 to become free. Usage

I could find that eth2 got renamed quite a few time:
dmesg | grep eth2 | grep renamed
