Maybe the issue below is affecting indirectly.

At commit 9562994a7aacee2baae6ddee1a7b558b48ae39ef,
tunable debug.link_elf_obj_leak_locals was flipped to 0 (true),
causing nvidia.ko with default options of x11/nvidia-kmod*
to fail loading, causing nvidia-modeset.ko to fail, then,
nvidia-drm.ko to fail, too.

Even without LINUX option enabled (non-default), nvidia-modeset.ko
still fail as of the lack of (formerly available) local symbols in
nvidia.ko. And nvidia-drm.ko wants local symbols in nvidia-modeset.ko.

Patch at Bug 291232 (the same patch is available via review D53987)
would fix the issue.

Note that commit 9562994a7aacee2baae6ddee1a7b558b48ae39ef is
temporarily reverted at commit fad4c92b78a123f87195173ac118655fa8e325cd.

And I predict commit e00a781c216cb12603a0a71c9ca293dde3e06250 would
allow linux*.ko to be loaded, thus, LINUX option would hopefully
become safe to enble again.

(I've put links to the PR and review in another post.)

I have only one computer for FreeBSD, having 2 SSDs for stable/15
and main respectively, so to test on main, I need to reboot into
main environment (which is outdated and need upgrading first
to obtain commit e00a781c216cb12603a0a71c9ca293dde3e06250).
So untested on main branch, nor on recent models of GPUs.

Regards.
