Comment 1 John W. Linville 2012-07-26 15:07:49 EDT
Johannes, any interest in this?  What does that WARN_ON in __cfg80211_send_disassoc signify?
Comment 2 Johannes Berg 2012-07-26 15:18:54 EDT
Hmm. It means that we did a disassoc while we were associated, but the current_bss pointer didn't match. I guess we need to make that warning print out a lot more info to figure out what's going on.
