The same thing happen to me after flashing Miko 4.5, Kernel Netarchy Toastmod 4.3.2 CFS more HAVS nosbc. it works fine but start acting up on reboot and sit at the white screen only after flash the kernel. I go back to Netarchy Toastmod 4.3.1 CFS HAVS nosbc and now it is working good. Not sure if Netarchy Toastmod 4.3.2 CFS more HAVS nosbc is still in Beta and that is the reason. This Kernel did the same with Miko 4.4
and will more than likely flash Mik's 4.5 this weekend.
