zfs/zpool encryption crash on server 21.10

Hi,

just installed a new HPE microserver with SSD and four harddisks with new 21.10 server and tried to create a zpool with

zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd -O encryption=on -O keyformat=passphrase

which reproducably crashed twice with the attached kernel message.

The zpool then exists, but is not encrypted.

zpool create pool1 raidz2 /dev/sda /dev/sdb /dev/sdc /dev/sdd
without the option works

and a subsequent

zfs create pool1/sub -o encryption=on -o keyformat=passphrase

works as well. Which is, however, not a real workaround for a fully encrypted pool (which worked under 20.04).

regards
