Hm. Maybe this is the problem?

I don't see any code that matches that in 3.3.0 (nothing with nl80211_start_ap, for instance)

ah, well, it's set_beacon there or so

I tried this patch, but it still spews (see below)

WARNING: at /home/greearb/git/linux-3.3.dev.y/net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x26/0x2b [mac80211]()

   [<f96a3438>] ieee80211_set_txq_params+0x97/0xec [mac80211]

but now it's coming from elsewhere, see this patch?

http://p.sipsolutions.net/b8506c9d7ce8a119.txt

That fixes the problem for me, or at least the easily-reproducible part.

I did have to modify the patch to work on 3.3.0 since it has no start_ap
and the beacon method is named a bit differently.

I'm going to apply this to my patch set and will let you know if
I see anything else strange.

Thanks!
