I forgot to put some informations about our test, so the information
that (a)"What we're doning" and (b)"runtime diagnostic" are as follows.
(a)"What we're doning"
We are doing hotplug test about USB Host Controller(HC) by inserting
and ejecting HC and USB devices. The panic was happened by eject test.
The eject test is that we eject USB devices from the HC and after
about 1 second we eject the HC itself from the machine.
(b)"runtime diagnostic"
1) USB devices are connected to the HC
USB device: CD-ROM, Keyboard, Mouse
--start test--
2) eject USB devices from HC
about 1 second
3) eject HC from the machine
!!!! Panic was happened !!!!
