This one works, but without GUI, probably because I forgot to install
any WM/DE, but something seems to be running on tty7 and tty8, so I'm
assuming it's slim-service.

>/var/log/messages looks normal to me.
No way, even if it looks on this partition I tried only installing Guix
System and it never worked.

Yes, the system didn't respond at all - i couldn't even switch to
another tty, so Alt+SysRq+B was the only thing working, but sometimes i
had to hard reset the computer, because even this didn't work.

Everything I saw was a frozen console, even the cursor wasn't blinking.

The partition was formatted once, but as I said before, only Guix
System ran on this partition and it never worked, so that's how the log
looks like, when I can't do anything.

I tried installing Trisquel 8.0 to check if this is a bug in the
linux-libre kernel, but it even stopped working during installation
time. On the other hand installing Devuan works and it boots from the
SSD (if Devuan's installer is the same as Debian's, then it works).
But I can try installing Debian if it is necessary.

Anyway, even if UEFI mode is enabled, the system works only with the
GPU disabled in grub.

For me, personally this sounds like an issue with Linux and Linux-libre
generally. Once about two months my system (even when using blobs)
freezes just like during early boot of Guix System. Maybe everything
is okay with the system, except the GPU driver - the screen freezes,
but the system continues to work. It's probably a problem with Linux,
because Windows 10, on the same computer, rarely crashes (by this I
mean it rarely freezes in this particular way, because it crashes a
lot, but with a sad smile ':(').
