to your comment:
Also I'm pretty sure that with openwrt 15.05.1 and kernel 3.18.23 there is no such rcu problem at all.

Yes, you are right, i tested the old wrt kernel 3.x .. and is not having such kind of problems.
also tested from manufacturer the image, this is the stablest one. but useless as totally out of date.
