JFYI, I bisected this issue to the following patch:
commit 58d5af59d55b4e9f3015207afa6a6648e9b005b1

sched/topology: Introduce NUMA identity node sched domain
On AMD Family17h-based (EPYC) system, a logical NUMA node can contain
upto 8 cores (16 threads) with the following topology.
which either exposes or causes this issue.
