Freeze @ reboot, shutdown etc

I’m gonna include the edits in above post:

Well, it works for me, it’s just the reboot/shotdown that doesn’t (and small bugs here and there, kinda expected from wayland+nvidia at the moment.
I was looking into THIS but wanted to fix the other things first, besides, from what I have read, even if I run sddm in wayland it will still change tty on login judging from the comments on THIS.

Yes.

Internal, connected to SATA.

I have not, I will try that.

Now that you mention it, I sometimes use a different wifi because it has higher speeds, and if I switch that without disconnecting the smb share (its only available on the first network) manjaro acts suuuuuuper sluggy until I umount the smb drive, and when restarting then, it has never failed, but it takes a loooong time. I will look into this.
Is there a way to force unmounting before network interface disconnection?
