[Q] Home screen 'hangs' on Asylum CM10 rom

I flashed asylum rom and sometimes(not every single time,more like periodically) when i try to unlock my phone, the screen would flicker and go blank. i will have to wait for bout 30 sec b4 attempting to unlock the phone from black screen.

I have Noled app installed but i am not sure if this app has anything to do with it. Would appreciate if anyone could enlighten me.
