Amazingly the RC4 kernels booted! I tried both low latency and generic
and problem is still there.
It may be unrelated but I think it is worth mentioning never the less. I
have problems with keyboard skipping keypresses (Eg. forgets that I keep
my finger on CTRL key, does C instead of CTRL-C etc.), touchpad palm
detection not functioning (yes tried to enable it), grub breaking
windows hibernation/fastboot (had to put windows boot loader to do the
booting), amdgpu-pro drivers crashing, wifi rtl8723be needing driver
from github. Yeah, things are barely functioning here :(
