All 9 BSS accepts clients. But when I "Ctrl + C" or "killall hostapd", hostapd daemon can NOT gracefully shut down. It hangs forever. I have to "Ctrl + C" again. Then it quits and print message like " I am running latest (as of 01/06/2011) hostapd, latest stable kernel (2.6.37) with one number change in ath9k to allow more than 12 virtual BSS over one radio. Below is my hostapd-conf and console screenshot. If someone can fix this bug, please help.
