Might be related to
https://bugzilla.redhat.com/show_bug.cgi?id=519208. I filed that bug
almost two months ago and there has been no motion on it whatsoever.
I've tried the same scenario again recently with similar results.|
Personally, I've given up on NetworkManager until I see some sign that somebody is actively working on making it stable and fully supporting it. If a user files a bug report about serious breakage like this and nothing has been done with it almost two months later, that seems to me like a pretty clear sign that the package is not ready for prime-time.
If NetworkManager is considered a F12 core feature, then the bug I filed should probably be an F12Blocker, but I didn't mark it as such because I don't know if it's a core feature.
