status 12 is:

        HAL_EINVAL      = 12,   /* Invalid parameter to function */

(from ah.h).  The first flags translate to a 2GHz Dynamic Turbo channel 
(see _ieee80211.h).  The hal flags translate to a 5GHz Dynamic Turbo 
channel (see ah.h).

So the driver is mis-mapping the channel and causing the hal to reject 
the request.  If I recall this causes scanning to stop on RELENG_7 so 
you'll want to force this channel to not be requested by disabling 
dynamic turbo mode.  I can't recall how that's done on RELENG_7; consult 
ifconfig(8).
