Support for Windows Vista Service Pack 1 (SP1) ends on July 12, 2011. To continue receiving security updates for Windows, make sure you're running Windows Vista with Service Pack 2 (SP2). For more information, refer to this Microsoft web page: Support is ending for some versions of Windows.

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 or Windows Vista Service Pack 1.

  • The computer has a Peripheral Component Interconnect (PCI) Express interface.

  • You have at least one PCI Express card that does not fully support Active State Power Management (ASPM) inserted.

  • You restart the computer.

In this scenario, an internal error may occur during restart. For example, a CPU IERR error may occur. Additionally, the system may stop responding.

This problem occurs approximately one time in every 500 restarts. Therefore, you usually experience this issue only when you are running restart tests. However, the risk of this problem occurring increases significantly if the following conditions are true:

  • You apply hotfix 952681 on the computer.

  • You insert PCI Express cards that do not fully support ASPM into all available PCI Express slots.
