Help with chaco kernel please!

[jeannnnn]

Hi,
I installed with my recovery the chaco kernelhttp://forum.xda-developers.com/galaxy-s4-mini/development/kernel-chaco-t3121267 for cm12.1, When I rebooted the phone stuck all the night on cyanogen's logo.
I made a backup before but I want to know why?

Sorry for my bad english I'm french!
Thanks.
