Yes, it's a known problem.  It's very reproducible for me on a non-hacked 3.3-rc1 as well: changing from AP to client mode, or setting up multiple APs, or changing from 2.4Ghz to 5Ghz all seem to trigger this warning with various stack traces.

I'm still seeing this and related warnings on 3.3.0.  At least some
of them comes from calls the 'hostapd' process makes (I printed
current->comm in the warning).

I am not having luck writing a simple script that reproduce this,
but my application that creates a VAP and bunch of virtual station
hits it every time on startup.

Bryan:  Do you have a simple script that reproduces this problem?

Johannes:  Any ideas on likely causes of this problem?  Might help
me zero in on the problem quicker...

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)

Thanks,
Ben
