After upgrading to the 4.10 ck kernel, I began to notice spiking on my panel cpu meter. Opening top, I noticed that the processes that spike are Xorg, lxpanel, and rcu_preempt. These things spike from 20 to 200% according to top, but mostly 10-30%.
Occasionally other things if they are open, but I'm not sure if that is related.
I changed to the vanilla kernel and it appeared to stop. I noticed that ck had changed to 4.11 and it still seems to do it.
Disabling the bfq scheduler doesn't seem to do anything.

Recommend you report the behavior to ck's blog for investigation.
CPU-optimized Linux-ck packages @ Repo-ck • AUR packages • Zsh and other configs
