unfortunately this doesn't make much sense to me :/
there's seems to be some CPU frequency scaling as well as TCP
receiving going on. but I have no idea how one would cause problems
for the other
(this doesn't mean that there's no problem, it means that I'm not seeing it)

+Cc linux-arm-kernel and linux-kernel in hope that someone has an idea
