I have two new B2200 in a mesh network yesterday. Everything worked fine (also upgrade to 3.212).
Today, after the advertised upgrade from 3.212 to 3.215, this situation is completely different:
The main node is on 3.215, but the sub node remains on 3.212. The 2.4 GHz WLAN seems to have stopped working.
LuCI shows the firmware version OpenWrt Chaos Calmer 15.05.1 e7067e3+r49254
(which is kind of old; I think, I remember seeing 19 something yesterday on 3.212).
Tons of kernel errors, like:

Wireless settings shown in LuCI are wrong (because of wrong OpenWRT version?)
Any suggestions how to fix this mess?
Thank you.
