At this point, eth1 is down and resolv.conf is empty except for the
NetworkManager comment mentioned before.

resolv.conf is okay now.

I have figured out that the resolv.conf update on my machine is
triggered when /sbin/dhclient is run, probably through
/sbin/dhclient-script.

resolv.conf is still okay; NetworkManager follows:

Yes, resolv.conf has been overwritten.

Only three more lines of output:

,----
| NetworkManager[27309]: <info> caught signal 15, shutting down normally.
| NetworkManager[27309]: <warn> quit request received, terminating...
| NetworkManager[27309]: <info> exiting (success)
`----

> Could you also send me the complete /etc/NetworkManager/NetworkManager.conf file.

,----[ /etc/NetworkManager/NetworkManager.conf ]
| [main]
| plugins=ifupdown,keyfile
| 
| [ifupdown]
| managed=false
`----

I hope that this helps.
