[Bug 259019] kld_list="radeonkms" in /etc/rc.conf -> kernel panic

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259019

--- Comment #4 from donaldcallen@gmail.com ---
@Ed Maste -- This has nothing to do with the syntax used to specify the syntax
used to specify the kernel module in rc.conf. Read on.

I have revisited this, as I am now using FreeBSD more widely than was the case
when I originally reported this. So I need it working reliably on the machine
with which I had the problem originally reported.

Reinstalling FreeBSD 13 on that machine, I found that with the line
KLD_LIST="radeonkms"
in rc.conf, the system would crash while booting, as I originally reported.

Installing xf86-video-ati made the situation slightly better. The system would
occasionally boot, but more often than not, it would crash while booting.

Additionally installing xf86-video-amdgpu solves the problem. Now the system
boots reliably.

I think the fix is either to make both of the xf86-video-* drivers dependencies
of the drm-kms package, or at the very least, fix the documentation to note
that if you are going to try to use the radeonkms driver on an old AMD-based
system, you need to install the two X drivers or you will have the serious
problem I encountered.
