While drm-current-kmod worked for a little while, it broke with r353645.

I'm using the same HP Spectre that I used earlier (where it worked and
where it panicked).
That commit looks unrelated, it touches the wbwd and superio drivers,
nothing else. Any chance you can bisect exactly which revision that
caused the new issues?
I believe it was the recent work on the vm page busy state, r353539
specifically. This patch should fix it; we don't yet have a
__FreeBSD_version number bump on which to gate the patch.

Hi!
Hopefully someone can confirm that this patch to drm-current-kmod or
drm-devel-kmod fixes the issue. I won't be able to work on this before
the weekend at the earliest, I'm afraid.
Mark, is it possible to get a belated version bump for this fix, and
what changed to require it?
I committed the bump and verified the patch on amdgpu. Here are some
PRs for the drivers:

https://github.com/FreeBSDDesktop/kms-drm/pull/181
Hi!
I'm working on getting this into the versions that are in ports. For
drm-current-kmod it's fairly simple, but for drm-devel-kmod there are
unrelated changes which I need to check if they are ready to go in or
not, so it will take some more time.
Looking at the mail list thread, there seems to be a patch needed for
base as well, has this been committed?
Regards
