--- Comment #1 from Ed Maste <emaste@freebsd.org> ---
14.2 incompatibility 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.

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