The system is running OpenWrt with kernel 2.6.30.10 on Asus WL-500GP
(brcm47xx system mips) and hostap git of 2010-01-08.
The Systems and hostapd starts normal, but if a client tries to
connect to the access point the AP crashes. Without encryption it
works without any problems but with PSK and WPA1 the system crashes
with the attached panic. I have not tried other encryption modes. With
compat-wireless of 2009-12-05 and hostap git of 2009-11-29 the system
worked link expected.
Much the same behavior w/ OpenWrt & 2.6.31.11 on Alix (x86), AR9160
radio (ath9k) and above compat-wireless and hostapd using WPA2.
I also got some warnings on the client. It was running the same
hardware, kernel and compat-wireless w/ wpa_supplicant 0.6.9.
