cat /etc/default/grub

Sorry guys, the fault was in grub.

sysrq_always_enabled=1 was in grub to load at boot. this was the culprit, I’m sorry.
I forgot about it when I put it there when I followed this tutorial:

[HowTo] reboot / turn off your frozen computer: REISUB/REISUO

Difficulty: ★★☆☆☆ This tutorial was created because people are using a hard power off during freezes, so this will teach you how to turn off your computer when everything is frozen using softer means. So whenever you see someone saying they had to “Power Off” or “Hard Reset” their system without doing a REISUB, please send them here!
