Hi, I got two reports in the last three days from people who have traces showing the driver attaching, scanning and starting to authenticate/associate and (in one case) apparently having succeeded but then bounce back to scanning. The two cases are different but essentially mean net80211 or iwlwifi/firmware didn't see some frames it expected (or there is also a possibility of a logic bug between mac80211/iwlwifi still; I had cherry-picked some fixes for that already). Long story short: in the follow-up of the auth_to_scan change people are seeing firmware crashes or in a follow-up even a panic. I'll be looking into those the first days in the New Year. If you have such a case please make sure to turn on wlandebug with "+auth +scan +state +node" at least (see wiki for how to do this in rc.conf [1]) and drop me a private email with the log.
