Back screen when you lock it and screen goes off and wont turn off after minutes or restart? When this happens phone turns off almost everything to save battery (mostly in custom ROMs). Try using "SetCPU" app from play store and try increasing minumum clock rate of processor. Link to app https://play.google.com/store/apps/details?id=com.mhuang.overclocking&hl=en

Also are you using "Greenify" ? If yes see that system apps aren't selected.

If this doesn't work you can see if any other kernels are available for your device else report this isssue to Cyanogenmod developers.
