Consider the following scenario:

• You have a computer that is running Windows Vista or Windows Server 2008.
• A compact flash (CF) card is plugged into a CF card slot on the computer.
• You try to resume the computer from hibernation (S4).

In this scenario, the computer may stop responding instead of resuming correctly. Eventually, you may receive the following Stop error message:

*** STOP: 0×0000009F (parameter1, parameter2, parameter3, parameter4)
DRIVER_POWER_STATE_FAILURE

This problem occurs only occasionally.

Consider the following scenario:

• Windows Server 2008 or a Windows Vista SP1 is running in a virtual machine.
• The computer that is running the virtual machine has multiple processors.

In this scenario, the virtual machine may restart unexpectedly. Additionally, you may receive the following Stop error code:

0×000000BE

On a computer that is running Windows Server 2008, Windows Vista, or Windows Vista Service Pack 1 (SP1), you may receive the following Stop error message:

0×000000D1 ( parameter1 , parameter2 , parameter3 , parameter4 ) DRIVER_IRQL_NOT_LESS_OR_EQUAL

Notes

• The four parameters in this error message vary, depending on the computer’s configuration.
• Not all “0×000000D1″ Stop errors are caused by this problem.

Typically, this issue occurs on a multiprocessor computer.

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.

You are running a Windows Vista-based or a Windows Server 2008-based computer that has an internal USB device installed. When the computer enters sleep mode, the computer may stop responding. Additionally, you may receive the following Stop error:

Stop 0×000000FE (00000008, 00000006, 00000002, parameter4)
BUGCODE_USB_DRIVER

Note: In this error message, the value of the Parameter4 may vary.

On a Windows Vista SP1-based computer or on a Windows Server 2008-based computer, you have update 941649 or update 944020 installed. When you try to attach a Niveus Ice Vault Disc Changer to this computer, the operating system may stop responding. Additionally, you receive the following Stop error message:

STOP: 0×0000007E (C0000005, Parameter2, Parameter3, Parameter4)
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED

When you restart a multicore-processor computer that is running Windows Vista, you may receive the following Stop error message:

STOP 0×0000007B (parameter1, parameter2, parameter3, parameter4)
INACCESSIBLE_BOOT_DEVICE

This problem is more likely to occur on a virtual machine.

Consider the following scenario:

• You have a computer that is running Windows Server 2008 or Windows Vista.
• Multicast forwarding is enabled.

In this scenario, the system may restart repeatedly with different Stop error codes, such as 0×0000001E or 0×000000D1. Or, the system may stop responding. This problem does not occur if you disable multicast forwarding.

A Windows Vista-based computer or a Windows Server 2008-based computer may restart unexpectedly. Additionally, you may receive a Stop error message that resembles the following:

*** STOP: 0×0000010E (0×00000002, 0×00000001, 0×00000000, 0×00000000)
VIDEO_MEMORY_MANAGEMENT_INTERNAL

Note: The four parameters in the “STOP 0×0000010E” error message may vary, depending on the actual configurations.

This problem typically occurs when you are running an application that requires lots of graphics processing. For example, this problem may occur when you play a video game on the computer.

A computer that is running an x64-based version of Windows Server 2003, of Windows Vista, or of Windows Server 2008 randomly restarts and then generates a Stop error. The Stop error code may be 0×0000001E, 0×000000D1, or another Stop error code.

This problem occurs after you install update 932596 on the computer.
