Consider the following scenario. You are running Windows Vista or Windows Server 2008 on a computer that has multi-core processors. A driver on the computer calls the MmProbeAndLockPages routine asynchronously. In this scenario, data corruption may occur.

This problem occurs randomly. It typically occurs when the following conditions are true:

• The computer has some graphics processing devices installed.
• You are running a graphics-intensive application.

When this problem occurs, the system or the application may crash. The actual symptoms vary, depending on the specific drivers that are installed on the computer.
