hi .

  The kernel panic is coming when i upgrade the hostapd to 0.6.9. In the version i previously used is 0.4.8.In that version there is no  kernel panic and the system works fine. if it is not a hostapd issue then the panic should come in 0.4.8 version . But in my case its not coming . 

And In the System Kernel(linux-2.4.25) , Wireless Driver (madwifi-ng),  I didn't change anything in that . 

As i said when Vap2 entered promiscuous mode its try to get the security settings. there only kernel panic starts.
here is kernel log :
<6>device ath1 entered promiscuous mode
