Kernel Crash on starting hostapd

[ravin goyal]

Hello, I have a banana pi m2+ running raspbian lite 3.4.112-sun8i

I am using using hostapd v2.7-devel-hostap_2_6-690-gb5562a1
following thread on banana pi forum link:

http://forum.lemaker.org/thread-11676-1-1.html

I have managed to configure and run successfully on my wlan0 interface
and for that I have to do

modprobe -v bcmdhd op_mode=2

command before starting it.

It was running successfully but after some time I stopped it and tried
to run again in daemon mode it returns segmentation fault following
kernel crash message.

I reboot the device and on boot it starts and it is working fine for
atleast now.

Any help appreciated?

Ravin
