Hi,
This seems newish, maybe 4.16 debug kernels were doing it also, but
I've seen if for all of 4.17. But what's new, I think, with
4.17.0-0.rc5.git1.1.fc29.x86_64 is I'm seeing a 4 kidle_inject threads
each using around 20% CPU per top, and the everything is sluggish, the
mouse arrow jerks around on screen, and apps aren't responsive.
I'm not sure where to start with troubleshooting; my first thought is
to just wait for rc6 and see if it's still happening.
Is this only visible in debug kernels, or do non debug kernels do it as
well?
