--- Comment #2 from Ed Maste <emaste@freebsd.org> ---
Issue with drm-kmod is noted in the 14.2 errata (but not release notes,
unfortunately) https://www.freebsd.org/releases/14.2R/errata/:

> drm-kmod packages compiled on FreeBSD 14.1 result in the text console being
> inoperative when the kernel module is loaded. Recompiling the package from the
> ports tree will restore the lost functionality. This issue will also resolve itself
> after the FreeBSD 14.1 EoL, when packages for 14-STABLE will start being built on
> FreeBSD 14.2-RELEASE.

As Mark says please try rebuilding graphics/drm-kmod against your updated
kernel source, and let us know if that resolves the issue. We need to solve
this in a better / holistic way, but this will hopefully get things working for
you in the short term.
