Battery Low [Q] Device Encryption 4.2.x / 4.3.x

Is anyone else experiencing broken device encryption? I theorize its related to the enforcing/permissive issue. I struggle to get my modem to stay, & at times it shows my other lines info! To attempt a resolve I have flashed several kernels from 4.4.2 l900 roms like carbon, cm, pa on cm base, If baseband is still breaking I go back to LJC for a fix then jump to 4.3. And encryption remains busted on TW or CM.
