Comment 28 for bug 83623

I upgraded to the packages here:

https://bugs.edge.launchpad.net/ubuntu/+source/network-manager/+bug/145683/comments/15

It's too early to tell if the suspend hang will happen (only tried it once and it didn't hang), but I did notice that the NM was much more responsive after resume. Previously it would take a minute or longer to finally get its act together and reconnect after resume, but with the new packages it was reconnecting by the time I had unlocked the computer.

Will post more as I find it.
