Default Blue screen when waking up phone

Hello, as the title says i have a blue screen when waking up phone. I am using Latest CM11 by arco running hurtsky kernel no other tweaks just installed... What could be the problem?

EDIT : Fixed it, the rom wasn't downloaded correctly and it caused errors
