Rechecked, things are still broken on platforms with non-linear numa zones.
But that isn't a bug in Ubuntu but a bug in upstream.
Worth to mention again, upstream on this project seems dead.
Due to its specific issue only affecting power machines with their numa layout that would IMHO be the HW-enablement team of IBM that drives this effort more than any other involved entity.
We will keep numad as-is for now as there are many other platforms it works (even some ppc64el systems), but the bug is "on IBM".
@Frank can you make sure that it is clear that the action on this is on IBM PPC people?
Once resolved feel free to update this bug, which then opens the opportunity to reconsider SRus for this and bug 1832915.
