it's stable with a custom kernel without magisk but causes it to crash then stuck on boot with magisk.

Phone specs:

-Nexus 6

-System version: mob31k

-Kernel: stock then flashed Hydra v5.0-[01-23]-[00-08]

-Magisk Version: v9

-su version: phh su 266-2

EDIT:

uh... might be my kernel.

going to try stock kernel with magisk.

EDIT 2: Guess it was my kernel... my bad...
