Memory hotplug failed to offline on bare metal system of multiple nodes

Hi, A hot removal failure was met on one bare metal system with 8 nodes, and node1~7 are all hotpluggable and 'movable_node' is set. When try to check value of /sys/devices/system/node/node1/memory*/removable, found some of them are 0, namely un-removable. And a back trace will always be seen.
