One thing--starting on the second iteration, I am seeing the WARN in free_area_init_node(); add_memory add_memory_resource hotadd_new_pgdat free_area_init_node WARN_ON(pgdat->nr_zones || pgdat->kswapd_classzone_idx);Have you tested with my attempts/rewrite-mem_hotplug-WIP mentioned elsewhere? Because I suspect that "mm: get rid of zone_is_initialized" might cause this.
This was my first time using your git branch instead of applying the patches from this thread to v4.11-rc5 myself.
