NetBSD shinji.studiolab45.net 6.1 NetBSD 6.1 (GENERIC) i386
>Description:
The system will completely freeze if a host connects to a wireless card using the ath driver when it is set in hostap mode.  There's not even a kernel panic; the whole system freezes.  This does not happen if the card is in adhoc or infrastructure  mode.

This issue also exists in NetBSD 6.0.  It did not exist in NetBSD 5.1 or 5.0.
>How-To-Repeat:
Set the card using the ath driver to hostap mode and have a device connect to it.

 machine freezes when using ath in hostap 

 the ath  driver  freezes the machine when switch to hostap mode using
 NetBSD-10.0_BETA
 steps:
 boot the macine, (it show ath0)
 ifconfig ath0 mediaopt hostap mode autoselect  192.168.168.1
 ===========/etc/dhcp.conf==============

 ddns-update-style interim;
 authoritative;
 option domain-name-servers 192.168.6.1;
 option domain-name "homecasa";
 subnet 192.168.168.0 netmask 255.255.255.0 {
 	option routers 192.168.168.1;
 	range 192.168.168.2 192.168.168.120;
 	next-server 192.168.168.1;
 }
 =============/etc/hostapd.conf==========

 =======================================
 RUNNING.....
 service dhcpd onestart
 service hostapd onestart

 the system continues running, shows the network
 in AP mode on the android phone...  

 When connect to the network ssid=NetBSD asks for password.....
 the android phone gets the address and the machine
 freezes, only return after a hardware RESET of power-off-on
