[Xposed General] alatnet:
got the same thing with nexus 6 offical November patch (flashed system.img and boot.img).

seg fault saying that file descriptor tables cant be constructed or something.

EDIT:

Correction, might be magisk...

Booted fine with a custom kernel but installed magisk and i get a segfalt:

EDIT 2:

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 3:

ok then, might be my kernel...

going to try stock kernel with magisk.

EDIT 4: Guess it was my kernel... My bad...

EDIT 5: so it was my kernel. but im getting the xposed not active error.
