The server is a POWER9 Witherspoon AC922 (8335-GTC)
MAAS: version 3.2.6 (3.2.6-12016-g.19812b4da-0ubuntu1~20.04.1)
I've noticed this issue with Ubuntu 22.04 Jammy as the default release used for commissioning.
We need to run an alternative command to fetch hardware info on IBM POWER architecture as it lacks DMI table.
