The message is a ton of "ACPI Exception (acpi_memory-0492): AE_ERROR, handle is no memory device" In my emulation, number of memory devices are not so many (only 6), but, this messages are displayed 114 times. It is showed by acpi_memory_register_notify_handler() which is called by acpi_walk_namespace(). acpi_walk_namespace() parses all of ACPI's namespace and execute acpi_memory_register_notify_handler(). So, it is called for all of the device which is defined in namespace. If the parsing device is not memory, acpi_memhotplug ignores it due to "no match" and will parse next device. This is normal route, not an exception.
