SYMPTOMS

Scenario 1

You try to upgrade to Windows 7 or Windows Server 20008 R2 or to perform a clean install of Windows 7 or Windows Server 2008 R2 on a computer that uses a 1394 bus host controller. However, the computer stops responding during the installation process.

Scenario 2

You have a computer that is running Windows 7 or Windows Server 2008 R2. The computer may stop responding if one of the following conditions is true:
  • You disable and then enable the 1394 bus host controller.
  • You uninstall and then install the 1394 bus driver (1394ohci.sys).
  • You wake the computer from sleep.

CAUSE

This issue occurs because the 1394 bus driver in Windows 7 does not issue an Open Host Controller Interface (OHCI) Soft Reset command to the 1394 host controller. This occurs when the computer sets the device to a low power (D3) state. When the computer sets the 1394 host controller to a high power (D0) state, the host controller may generate an incorrect PCI-Express packet. In this situation, the motherboard chipset stops responding. 

Note In Windows Vista and in earlier versions of Windows, the 1394 bus driver issues an OHCI Soft Reset command to the 1394 host controller when the computer sets devices to a low power (D3) state.
