It will take me a bit to setup a separate build/install
context for the source code vintage involved. Then more
time to do the build, install, and test. (I'm keeping
my normal environments completely before the mess.)
FYI:
I have used the artifact build just after your pair of zfs
related updates to confirm the VFP problem is still in
place as of that point:
https://artifact.ci.freebsd.org/snapshot/main/5e2e3615d91f9c0c688987915ff5c8de23c22bde/arm64/aarch64/kernel.txz
(No artifact build was exactly at either of your commits.)
