Hmm. 2024-Jan/Feb/Mar are missing, as is about half of 2024-Apr.

The newest 2023 one seems to be:

137b36455d51f7303166bd4e1625b0bf969b9db5/ - 2023-Dec-28 07:48

that also boots just fine:

# uname -apKU
FreeBSD generic 14.0-STABLE FreeBSD 14.0-STABLE #0 137b364: Thu Dec 28 07:38:14 UTC 2023     root@FreeBSD-stable-14-aarch64-build.jail.ci.FreeBSD.org:/usr/obj/usr/src/arm64.aarch64/sys/GENERIC arm64 aarch64 1400502 1401000


The oldest 2024 looks to be:

58fdd8509cf1a6846cc4124c2bfa03d9343ab910/ - 2024-Apr-14 02:15

It has the problem that Mike reported.

So the untested range is about 3.5 months wide, unfortunately.
