Hi,

To be clear- the kernel can't find the zfs pool, or one of the earlier
stages? Giving the pool manually meaning at a mountroot prompt, or
somewhere else?

This is for specifically for aarch64, but you've not specifically
mentioned it- you're on aarch64, right?

I think we'll need a little more information about where and
specifically how it's failing for you to determine that. Others have
reported successful upgrades from 11.1 to 11.2 with root-on-ZFS
setups.
