I had this problem also after I updated my sources this morning in
Germany and decided to make a new kernel and world. I then booted the
new kernel and did installworld, after which I rebooted with the new
kernel and saw that the console disappeared after the BTX Loader
output appeared.
So I logged in using ssh and looked under /boot. There were 52 files
which had been newly installed, all of them related to booting.
Luckily, I had a backup of /boot which I'd made on January 1.
Restoring the backup got me back my console.
I have no idea which of the newly installed files caused the console
to disappear. Note that my loader.conf was not modified. And also
that I still use 4th rather than lua.
I tried using both sc and vt, but the console still failed to appear.
