Are you able to reproduce this by any chance? It's been happening for a
while, but I've so far been unable to figure out what causes
"wdev->sme_state" and "wdev->current_bss" to get out of sync ...
If you could reproduce, a trace would help.

Sorry, it only happend with the wireless network I tried to connect to
while I was on vacation. I was not able to reproduce it since but as
soon as I can reproduce it I while tell you.
