For the artifact builds available for arm64, testing
the kernels:

The last that has "shutdown -r now" working on the RPi4B I'm using:

    • git: 8b418c83d175 - main - cp: Adjust the sparse file tests. Dag-Erling Smørgrav
( https://artifact.ci.freebsd.org/snapshot/main/8b418c83d175fde3b1f65210509ddcf2ac248d9f/arm64/aarch64/kernel.txz )

No arm64 artifacts after that until . . .

The first that has "shutdown -r now" failing on the same RPi4B:

    • git: ded5f2954e1a - main - nfsd: Fix handling of the error case for nfsvno_open Rick Macklem
( https://artifact.ci.freebsd.org/snapshot/main/ded5f2954e1a1bb7748646888938af767ee6257a/arm64/aarch64/kernel.txz )

So the range is limited to (including those end points):
(All are 2023-Feb-08 artifact builds.)

Notable are the llvm15 commits and the changes that some arm code:

• git: 1d03c3578d05 - main - arm: add an interrupt rman to nexus Mitchell Horne 
• git: f9bdaab95ec4 - main - ofwbus: remove handling of resources from ofwbus Mitchell Horne 

https://artifact.ci.freebsd.org/snapshot/ helps avoid as many
builds being involved in exploring.
