Hi

So if 3.9 works and current kernel does not, the best way to address
the issue would be identify change that broke. Ideally if  bisecton
could be performed, but this can be hard taking that the problem is not
easy reproducible. Further difficultly comes from a fact that OpenWRT
has custom patches. So I suggest some kind of manual semi-bisection 
on OpenWRT repository with long testing, to find out first or close
to first OpenWRT change that start to broke things.

Cheers
Stanislaw
