Hi,
Unfortunately I haven't had the time to investigate this further, but
for me it did happen after getting de-authenticated from an AP and
attempting to re-authenticate. While re-authenticating, mac80211
appeared to request going into power save after transmitting the
corresponding control messages, preventing the re-authentication from
succeeding.
My assumption is, that the dynamic power save mechanism is somehow
getting triggered from the control message exchange - but, as I said, I
cannot be sure at this point.

The mac80211 sometimes requests power save entry while not associated - this
will cause problems, so prevent it if not associated. Go to powersave once
association is complete.
Does it? It's not supposed to, and I imagine that causing trouble with
other drivers too. Do you know how that happens?
I'll keep this patch for now. Later, if the issue with mac80211 is found and
fixed, we can remove the code if needed.
