Hi Felix, Zack, et al!

I'm not able to reproduce this issue with the information provided so
far or able to conclude what the issue is.. Unfortunately, this bug
report has become a bit of a hodgepodge. I'm not sure if all the me-too
reports are actually the same issue.

So, it would be immensly helpful, if someone can provide me with a
detailed description of his network setup (what interfaces are managed
by NetworkManager, what by ifupdown, what's the individual configuration
and available interfaces, etc.).
Then the exact circumstances, when this happens and if this happens
reliably and how it can be triggered.
Also, I'll need a verbose debug log from NetworkManager [1].

Ideally, someone provides steps how I can reproduce the issue myself
(e.g. by started from a basic/standard Debian Jessie installation).


Thanks,
Michael

[1] That means running NetworkManager (as root) with the following
command line arguments:
NetworkManager --no-daemon --log-level=DEBUG --debug
It's possible, that you need to remove the D-Bus activation symlinks,
i.e. run systemctl disable NetworkManager.service; systemctl stop
NetworkManager.service; <debug>; systemctl enable
NetworkManager.service; systemctl start NetworkManager.service
