Ahh, I see the subject line lists f9668e4 instead.

That is 8 commits more recent than what I built (as
reported in my initial reply and shown again later
below):

https://cgit.freebsd.org/src/log/?qt=range&q=f9668e4 reports
(in part) . . .

None of that looks like it should make a difference
vs. my buildworld buildkernel .

It still appears that the basic information required
to identify the issue in your context is likely missing.
