Well this problem goes back to November. The problem first appears in
my generation 19 ...

     19            GNU with Linux-Libre 4.14.2 (beta)           61 2017-11-30 
     18            GNU with Linux-Libre 4.13.12 (beta)          62 2017-11-11 

... which  correspond to ...

19 (GNU Guix)
18 (GNU Guix)

Note: The results cited below are WRT my most recent build done
yesterday, guix (GNU Guix)

The VGA displays ...

- BIOS prompt
- grub menu
- 'Booting GNU linux-libre ...'
- ~1 seconds of messages
- Blank screen w/ no cursor

... which differers in that there are a couple seconds of boot messages.

/home/g1# echo 123 > /dev/console

... shows nothing on the VGA or serial.
