Hi Rafael, Toshi,
When we hot-add an ACPI0004 device, we got the following warning:
acpi ACPI0004:01: Attempt to re-insert
The ACPI0004 device is a System Board in Fujitsu server, which has two numa nodes (processors and memory).
It seems that we reserved the ACPI_NOTIFY_DEVICE_CHECK event twice in acpi_hotplug_notify_cb().
According to bisect, this happens after the following commit:
From 68a67f6c78b80525d9b3c6672e7782de95e56a83 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" <rafael.j.wysocki@intel.com> Date: Sun, 3 Mar 2013 23:05:55 +0100 Subject: [PATCH 1/1] ACPI / container: Use common hotplug code
Switch the ACPI container driver to using common device hotplug code introduced previously. This reduces the driver down to a trivial definition and registration of a struct acpi_scan_handler object.

I'm now investigating this problem. If you have any idea about why this happens, please let me know.
Thanks. :)
