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. > The git logs in /usr/src aren't time-sequential, so maybe I shouldn't trust > those dates above (I pulled it ~Jan 3rd and let it compile overnight), but > I'm going to repull all the sources and recompile, just in case.
