Subject: ACPI/container: Hang forever when eject a acpi container

Hi all,
When running the test box with stable kernel(3.10.45), I eject a acpi container
(with two movable node,60 cpus, 64G memory) via the sysfs interface:
echo 1 > /sys/bus/acpi/devices/ACPI0004\:01/eject, but it hanged forever
after offlined all the memory and cpus, more specifically, after print out
"[58488.558000] ACPI: Device does not support D3cold".[1]
I try to trigger "kdump"(via nmi) to gain some info, but it does not work.
The dmesg output(gained via netconsole after "echo 1 > ..eject")config
are attached.

I also try the latest kernel, but the eject container seems failed. Nothing
happened when echo 1 to /sys/bus/acpi/devices/ACPI0004\:01/eject.

Any guys ran into similar problem? And any comments are welcome.
If you want more info that I can offer, just say it.

Thanks,
Gu
