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:

0×00000124

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.
