[OpenWrt-Devel] wireless scan/add functioning wrong on my MTK7620n board

I’ve built a firmware from git.openwrt.org/openwrt.git known as CHAOS CALMER (Bleeding Edge, r42657) for my MTK7620n board, it works well except this weird problem.
When I enable wifi, then trying to use iw dev wlan0 scan or trying to add secondary AP from luci interface, my board will reboot without any signs at all, when it rebooted, secondary AP was added, can be joined normally but I also found a call trace about rt2800lib.c during the initialisation process, I wonder is this happened on your boards? I only have limited hardware driver debug skill and if I want to fix it by myself, where to go first?
Thanks a lot~
HERE is the boot log.
///////////// When I enabled wifi, it works well and msg looks like this:
BusyBox v1.22.1 (2014-09-25 02:03:10 CST) built-in shell (ash)
