SYMPTOMS
Consider the following scenario.
 * You are running a Windows Server 2003-based computer.
 * You have USB devices connected to the computer. For example, you have a USB keyboard and a USB mouse connected.
 * You try to shut down or to restart the computer.

In this scenario, the shut-down process stops responding (hangs), and then the system displays a black screen. You have to manually turn off the computer to recover.



CAUSE
This problem occurs because a deadlock is introduced when the system cleans the USB I/O requests during the shut-down process.
