Ok, this fixes the problem partially :)  Now the interface comes up, 
olsrd detects the neighbour on eth1/wan and LQ/NLQ is getting better and 
better... until:

now the the interface times out every minute:

It looks like this ticket:
https://dev.openwrt.org/ticket/8438

I'm building a debug-kernel now to get a better stacktrace...
