I see in your other post that powering off & disconnected everything
worked. Not sure why, but if it occurs again can you please try:

1. Modifying /etc/network/interfaces to:

# The loopback network interface
auto lo
iface lo inet loopback

only and taking out or commenting out the:

# The primary network interface
auto eth0
iface eth0 inet dhcp

bits.

2. Modifying /etc/resolv.conf to:

nameserver 192.168.178.1

3. Provide the output of:
$ cat /etc/udev/rules.d/70-persistent-net.rules
and
$ cat /etc/iftab
and
$ sudo cat /var/run/network/ifstate

Thanks.
