as discussed already on IRC, what we consider "broken" is: the lockdep issue 
which Kalle (and maybe others?) reported for hwsim, but that does not affect 
ath9k. Probably a hwsim problem only.

For the other issue for which Marek Puzyniak sent a patch ("cfg80211: fix dfs 
channel state after stopping AP"), I don't think this is a bug which should be 
fixed, but intential to keep the channel AVAILABLE after leaving the AP on a 
channel. Let's discuss this in the thread for this patch ...

I don't know if there are other issues, but since it works for me I would 
suggest to drop this patch and keep DFS enabled for ath9k.

Thanks,
    Simon
