Yes, GENERIC kernel, very generic system in general.

It's alarming that DRM was broken for 14.1-RELEASE, since that's the release on
which  packages are built until at least March 31st:

https://www.freebsd.org/security/#sup

All port updates should be fully tested on the same release used for package
builds before being committed, or we'll have more serious regressions like this
one.  This point was stressed to me during my "apprenticeship" as a ports
committer.

Running 14.2-RELEASE or later before 14.1 EOL requires building kernel modules
from source, to avoid panics and other KBI compatibility issues.  I've run into
this many times with drm and vboxdrv modules over the years.  For that reason,
I stay with releases until EOL on my  production systems, to ensure stability
across binary updates.  This is the first time the strategy has backfired.

...and it's actually stated in drm-kmod pkg-message:

<<<ROOT@coral.acadix>>> /home/bacon 1021 # pkg install drm-kmod

Message from drm-61-kmod-6.1.128.1401000_1:

--
The drm-61-kmod port can be enabled for amdgpu (for AMD
GPUs starting with the HD7000 series / Tahiti) or i915kms (for Intel
APUs starting with HD3000 / Sandy Bridge) through kld_list in
/etc/rc.conf. radeonkms for older AMD GPUs can be loaded and there are
some positive reports if EFI boot is NOT enabled.

For amdgpu: kld_list="amdgpu"
For Intel: kld_list="i915kms"
For radeonkms: kld_list="radeonkms"

Please ensure that all users requiring graphics are members of the
"video" group.

Please note that this package was built for FreeBSD 14.1.
If this is not your current running version, please rebuild
it from ports to prevent panics when loading the module.
