Ohh stupid question what hardware are you running this on,
specifically what SSD's and what controller and if relavent
what controller Firmware version?
I wonder if you might have bad HW / FW, such as older LSI
mps Firmware, which is know to causing corruption with
some delete methods.
Without the ashift fixes, you'll be sending short requests
to the disk which will then ignore them, so I can see a
potential corrilation there.
You could rule this out by disabling ZFS TRIM with
vfs.zfs.trim.enabled=0 in /boot/loader.conf
