OpenWrt support for Linksys MX4200

I built qosmio's NSS branch (qualcommax-6.x-nss-mx4300) with latest changes today and kernel version is 6.6.51. On the nodes, the mesh point RX rate, TX rate, signal, etc. is blank, like below.

If I restart radio2, then the data shows like below. Any ideas how to make it work after a reboot?
