A "0x00000124" Stop error message occurs when you use the "hot plugging" feature to add or to remove a PCI Express device on a Windows Server 2008-based computer or on a Windows Vista-based computer

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 Peripheral Component Interconnect (PCI) Express interface that supports the "hot plugging" feature on a Windows Server 2008-based computer or on a Windows Vista-based computer.

  • You connect a device to the root port of the PCI Express interface.

  • You use the "hot plugging" feature to add or to remove a PCI Express device on the computer.

In this scenario, the Windows Server 2008-based computer or the Windows Vista-based computer may be restarted unexpectedly. Additionally, you receive the following error message:

0x00000124

Note When you restart a Windows Server 2008-based computer or a Windows Vista-based computer, the issue may also occur if a PCI device is connected to the root port of the PCI-Express bus on the computer.

Cause

This issue occurs because resource rebalancing is triggered after you hot plug a PCI device. During the rebalancing process, the system does not configure the Max Payload Size value correctly on the root port of the PCI Express bus. The incorrect value causes a mismatch between the root port of the PCI Express bus and the device on the PCI Express bus. Therefore, the operating system triggers a Machine Check Architecture (MCA) exception, and the operating system returns a “0x00000124” exception.

Resolution

Windows Vista hotfix information

More Information

The PCI Express bus is a big technological improvement over the PCI bus. PCI Express provides better bandwidth. It also has an architecture that can be scaled to meet the requirements of the next generation of hardware and software.

PCI Express simplifies hardware requirements for hot plugging functionality. Users can now replace damaged system devices, such as network adapters and storage controllers, when a computer is running.


The resource rebalancing feature lets the operating system redistribute the resources that are allocated to I/O, to memory, and to interrupts when a device is hot plugged on the system. This feature is a more efficient and flexible resource allocation mechanism than the static resource allocation mechanism that is implemented in other Windows operating systems.

To see the devices that are listed under the PCI Express root port in Device Manager, follow these steps:

  1. Start Device Manager.

  2. Click View, and then click Devices by connection.

  3. Expand the PCI bus.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
