[SOLVED] only 3 cores working on 4 core cpu
Hello All,
Recently I've noticed using htop that only 3 of the cores are loaded fully. core0 always stays mostly in c6. Is this recent change in kernel ?
make -j4 bzImage to recompile the Linux kernel was always loading the 4 cores.

Linux blackbox 4.7.4-1-ARCH #1 SMP PREEMPT Thu Sep 15 15:24:29 CEST 2016 x86_64 GNU/Linux
Anyone else having this issue ?

Found the issue - is not kernel or hardware. Is about systemd CPUAffinity incorrectly set in system.conf

If I may ask, what motivated you to change that parameter in the first place?

Not exactly sure why it was changed but even so it was set to CPUAffinity=1 2 3 4 now I've commented this line and all works fine.
