Description Michael Jones 2015-12-14 07:38:32 UTC
I honestly don't know what information to post for this.

I have a hardened-sources-4.1.7 kernel that uses all of my cpu cores.

I copied the .config into hardened-sources-4.2.7, ran "make", pressed enter for every prompt to accept the default, and the resulting kernel will only use a single core, with very occasionally htop showing another core being used for a moment.

I've had this behavior happening for 4.2.6-r* as well.

What information would help debug this?

Reproducible: Always

That behaviour hit many people upgrading from 4.1.x to 4.2.y. See
https://bugzilla.kernel.org/show_bug.cgi?id=101021
https://www.reddit.com/r/linuxquestions/comments/3ja2kx/linux_42_using_only_one_core/

Change
CONFIG_NO_HZ_FULL=y
to
CONFIG_NO_HZ_IDLE=y
