--- Comment #3 from Dave Cottlehuber <dch@freebsd.org> ---
I added the post-corruption zpool here, reminder it's an arm64 boot image t=
hat
I see this assert on.

#openzfs irc commented:

i would suggest doing, is setting compatibility=3D and doing zpool upgrade =
with
different featuresets to narrow down what state might be going or just back=
ing
up the cloud disk images before first boot so you can compare on disk state
when
it worked and didn't

it doesn't seem to easily reproduce, but something to keep in mind, the VER=
IFY
that's tripping is an ASSERT, so it won't trigger on non-debug builds

but i can't immediately obviously reproduce it on my pi 4

something that would be useful, is if you can try only enabling spacemap_v2=
 or
log_spacemap, rather than just zpool upgrade -a and then seeing if it still
breaks.
