powerqaworker-qam-1 is down
Using Power On/Off System I did another try to explicitly power the system off, wait and on again.
Still not up, nsinger also has no luck to get the machine back over the HMC. Can't connect to that machine https://powerhmc1.arch.suse.de/dashboard/#resources/systems/aeaf3ef1-7d73-305c-9d9a-41d45801cf47/logical-partitions. To quote the HMC: "Das System ist Versionsabweichung".
so I removed the machine from salt for now to be able to apply the salt state again, see https://gitlab.suse.de/openqa/salt-states-openqa/-/jobs/159645 for a failure.
sudo salt-key -y -d powerqaworker-qam-1
