I think it would be good to do this, but it doesn't seem to be something that Debian does as a matter of course, and I'm unlikely to be the right person to lead such an analysis. It might be worth proposing this to the release team (debian-release mailing list).

Between the sample bias of bug reports > themselves and the “fog of war” neither conclusion is clear. I'm afraid I still don't have a deep enough understanding of the bug to say for sure. Given that 'numa=off' appears to be a workaround, I suspect that it is triggered by multiple NUMA nodes. That would imply that older multi-socket systems with a shared memory controller would not be affected, while some single-socket systems with multiple memory controllers would be affected.
