even with lede from november i got errors.
so, every freifunk-meshnode has two olsr-crashes during startup, see 
text below. after that, the device will work properly.

on the end of the text a random (?) olsr-crash happened during normal 
operation time (LWP1955)  , but gdb doesnt gives me useful information.
