So it seems to have nothing specific to do with the rpool.

Title:
BUG: kernel NULL pointer dereference, address: 00000000000006c8
Status in zfs-linux package in Ubuntu:
Confirmed
Bug description:
I am trying to get rid of the bug#1906476, so I installed a new Ubuntu/Impish
on another Disk with an unencrypted rpool followed the tutorial at
https://openzfs.github.io/openzfs-docs/Getting%20Started/Ubuntu/Ubuntu%2020.04%20Root%20on%20ZFS.html
After installation I copied the most from the encrypted disk to the
unencrypted one via booting from stick, importing encrypted rpool and
unencrypted rpool and using rsync.
The first reboot into the new disk hits another Bug:
