I've tested this patch, but it does not help.
The boot message is attached.
I tested on a arm board with 128 cores 4 numa nodes, but I set CONFIG_NR_CPUS=72.
Then node 3 is not be created, because node 3 has no memory, and no cpu.
But some pci device may related to node 3, which be set in ACPI table.
165 /* Interface called from ACPI code to setup PCI host controller */
166 struct pci_bus *pci_acpi_scan_root(struct acpi_pci_root *root)
167 {
168 int node = acpi_get_node(root->device->handle);
169 struct acpi_pci_generic_root_info *ri;
170 struct pci_bus *bus, *child;
171 struct acpi_pci_root_ops *root_ops;
172
// this node may be not created.
177 ri = kzalloc_node(sizeof(*ri), GFP_KERNEL, node);
178 if (!ri)
179 return NULL;
180
181 root_ops = kzalloc_node(sizeof(*root_ops), GFP_KERNEL, node);
182 if (!root_ops) {
183 kfree(ri);
184 return NULL;
185 }
186
187 ri->cfg = pci_acpi_setup_ecam_mapping(root);
188 if (!ri->cfg) {
189 kfree(ri);
190 kfree(root_ops);
191 return NULL;
192 }
