Is this also an issue in 6.9-rc1 or newer or 6.8.3 or newer?

It is not an issue with 6.9-rc1. 6.9-rc1 just boots fine.

Bah. That's my fault.

So before the topology evaluation rework landed in the 6.9 merge window this eventual double registration was harmless and only happening for a particular set of AMD machines. The topo rework restructured the whole procedure and caused the new warnings to trigger.

So the Fixes tag I added to that commit was pointing at the wrong place and this needs to be reverted from all pre 6.9 stable kernels.

Sorry for the inconvenience.

Thanks,
