FWIW, I'm on a Verizon variant running this rom with the lastest BlackBird kernel and I have no force closes whatsoever. NFC works and I haven't run into any problems yet except my memory ran out once.
IS there a custom kernel; in this ROM? or is it straight CM source? There is a very very low number of CM/AOSP kernels for the HTC One M8 available at the moment fro Android 5.1 and it would be great if you could share a flashable zip of the custom if custom. Thanks in advance!
