As per IRC discussion; there seems to be issues with, as a first step, the device not activating properly. There's microcode errors in the logs and I sadly don't know enough about the driver internals to go deeper there; but I do think it deserves investigation. The microcode errors (with what looks to me like timing issues) and the direct probes timing out are probably linked -- I'm adding a task for 'linux'.

The second issue is with the authentication windows popping up and stacking over one another rather than just ever keeping one window around. That's an issue with auto-activation that should be fixed in git already, but will need further testing -- I should prepare ppa packages for that.

Changed in network-manager (Ubuntu):
status: New → Triaged
importance: Undecided → Medium
importance: Medium → High

Then that the wpa crashes in nla_put(); I suspect it's just a side effect of the driver disappearing, when it does so at just the right time... I certainly can't think of another explanation for it.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1021516

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.
