I ran into a similar issue with a computer I installed Guix on.  It
would not complete the boot up process.  I am not sure if I was
experiencing the same issue you are as I did not submit it to a Guix
mailing list.  I got help solving it on #guix.  What worked for me was
to add the Linux kernel argument `nomodeset` to my system configuration.
In the operating system declaration of the system configuration I added:

```
  (kernel-arguments
   (append
    (list "nomodeset")
    %default-kernel-arguments))
```
