Hi Steven,

It's probably a bug fix that unveils the link errors.

I've no idea why this has been bisected to my commit. I repeated the
bisection manually and that fingered:

a55c7454a8c8 ("sched/topology: Improve load balancing on AMD EPYC systems")

which certainly looks like it could be the culprit given it introduces
the node_reclaim_distance variable.

Hi Steve,

Sorry for the inconvenience, the report is a false positive,
we are investigating the cause of the error.
