If it is just for testing then you should:

1. convert this PR to draft (since it is not read yet)
2. use a temporary patch like ldorau@a590c27 on my DEBUG_CI_run_only_multi_numa branch to test only one CI job that you are changing and do not occupy other resources, when you do not need them (the resources in public UMF CI are very limited).

It look like you did not started the GHA runner on the SLES15 machine, maybe ?
