I would recommend using hostapd 0.7.0 or a snapshot from the
development branch when using any mac80211-based driver like ath9k.

How did you configure the channel in hostapd.conf (both hw_mode and
channel values)? Based on the "(2)" there, it looks like you tried to
use 5 GHz band (hw_mode=a) and the driver did not allow AP mode
operation on the channel. You can use "iw list" to get a list of
channels that the driver reports as supported (AP mode cannot currently
be enabled on channels that require radar detection or do not allow
IBSS/Beaconing). I would assume that you will have better luck if you
were to start with 2.4 GHz band (hw_mode=g and channel 1..11).
