Cannot set frequency on phy device in 3.9.0+ ??

Seems like this used to work. NIC is ath9k_htc driver, configured with one VAP and one station. Both are admin down, but still get EBUSY when trying to set the frequency. Seems like this used to work (on ath9k driver, at least).

[root@lec2010-ath9k-1 lanforge]# ifconfig wlan1
