It's sad, I'll look into what linux drivers are doing then.

TBH, this laptop had Windows 10 installed, and I used bluetooth to
connect keyboard/mouse, so all drivers were installed/used. Then I
installed FreeBSD on top of it, all without shutdown, and I didn't get
errors while booting installer or installed system. It's only when I
did finally poweroff it I started getting these errors on boot.
