[Bug 237544] graphics/drm-fbsd12.0-kmod: panic on 12-STABLE with Radeon HD 7450 (but not with drm-fbsd11.2-kmod)

> Ideally graphics/drm-*-kmod ports should have never been tied to a particular version of *FreeBSD*,

In theory that could have been done, but that would have been a nightmare to
manage.
Also I don't see why we should give the possibility to users to install old
drivers, instead we should fix bugs in newer version if one have a problem,
something that I and others do regularly based on reports. None of us are
upstream DRM developers and we don't know the code base much as we only look at
some parts when we have some problems. You can't expect us drm-kmod people
(mostly wulf@ Greg V and I currently) to magically fix every bug. You can't
also expect us to have all supported hardware to test.

> My two-core, ten-year-old desktop at $work with Radeon HD 4350/4550 (RV710) is running 2019'ish -CURRENT with drm-legacy-kmod-g20190213 and works flawlessly for many months, rebooting only when there's a power outage.

 Congratulation on running old code on old hardware. RV710 is 14 years old not
ten, and in the GPU world 4 years is a *lot*. It's also using the radeonkms
driver which have more or less been abandonware upstream for quite some time
and again none of us are AMD/Radeon developers.

 And something that *I* can do on all my Intel or AMD recent hardware.
 Did you open a PR here or on the github page for drm-kmod so we can (maybe)
help you ? (I don't remember a PR from you)

> Situation with graphics on FreeBSD had never been worse, AFAIR. :-(

This kind of comment is really hurtful, demotivating and simply mean.
