--- Comment #12 from Gleb Popov <arrowd@FreeBSD.org> ---
I bumped into this problem on my RockPro64 with SSD disk attached via an
adapter. The symptoms are all the same:

# OK
newfs /dev/nda0
# OK
mount /dev/nda0 /mnt
# spits a ton of "cylinder checksum failed" messages
echo asdasd > /mnt/asd

If I do instead

newfs /dev/nda0
# fixes a ton of cylinder groups
fsck_ffs -y /dev/nda0
mount /dev/nda0 /mnt
# OK
echo asdasd > /mnt/asd
