Odd behavior with the eth0 interface.

[tuxd3v]

Hello,
What is the output of:

Code:

ip link show

Does changing interfaces from ethx to enpxsy changes anything?
You can try in '/etc/default/grub' on parameter 'GRUB_CMDLINE_LINUX_DEFAULT':

Code:

net.ifnames=1 biosdevname=0

or if it doesn't work:

Code:

net.ifnames=0 biosdevname=0

Check if it has something to do with eudev renaming interfaces..
Regards
