Created attachment 186961 [details] .config of failing 4.2 kernel Since updating to linux 4.2 from 4.1.6, now only one core seems to be used. Everything is really slow and compile time way higher + htop reports only one core active (the other 7 are stuck at 0%) Not a lot of config changes since 4.1.6 (only make oldconfig).
