Second - instead of creating zpool, can you do some simple tests? Do "diskinfo -t /dev/da1", "newfs /dev/da1", and 'fsck /dev/da1"; this will show you whether the basic functionality works. If it does - try to set those in /boot/loader.conf: vfs.zfs.vdev.trim_on_init=0 vfs.zfs.trim.enabled=0 then reboot and try to create zpool.
