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:

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. :)
