[Magisk] paed808:
I use a Moto G 2014 (titan) running Lineage OS 14.1. After installing Magisk v14.1 beta ( dirty flashed over Magisk v14), the system hangs at a bootloop. I have a few modules like Viper4Android & Dolby Atmos Audmodlib by ahrion, but I'm not sure if those modules have anything to due with the bootloop considering other people above are having the same issue. I did capture a bit from a logcat if it's relevant.

This was captured by the time I noticed it was bootlooping:

To revert back I just flashed the Magisk 14 zip again. But before I did that, I extracted the boot.img from the Lineage zip and flashed the img in TWRP for good measure.

Before I tried out Magisk 14.1 I backed up /data/magisk.img to my SD card just in case things got messed up to avoid having to reinstall all the modules I use.
