>Description:
FreeBSD is crashing when wpa_supplicant is called upon boot on the Genesi Efika MX smartbook.

Since I can't copy and paste the result of the crash, I've taken pictures and put them here :
http://iaelu.net/~yom/efikamx/arm-eabi/

I got helped by @rayddteam ( ray@ ) on the EFNET IRC subnet, in the #bsdmips channel.

The Wireless network was a WPA Personal.

after some investigations with the help of ray@
we could at least gather this information with the addr2line command :
/root/EfikaMX/obj/arm.armv6/root/EfikaMX/src/efika_mx/tmp/usr/bin/addr2line -e /mnt/boot/kernel/kernel c035bc44
/root/EfikaMX/src/efika_mx/sys/net80211/ieee80211_radiotap.c:138

I hope these informations help you to fix the problem, if there is any solution.

>How-To-Repeat:
The r251405 revision of head sources do not enable the wireless adapter by default so ray@ gave me a patch to enable it.

You can find the diff here :
https://github.com/GuillaumeBibaut/EfikaMX

the file is named :
imx51_iomux.c.diff

which should be patched in
head/sys/arm/freescale/imx/

I also used the MAKE_EFIKA_MX.sh script to build FreeBSD, that I've modified a bit and is accessible in the github repo.
In the script you can find the configuration files.
This script is using the ARM EABI for testing, as asked by ray at .
