Symptoms

You installed Windows 7 or Windows Server 2008 R2 on a computer that has an nVidia MCP7A-GeForce 9300 rev B1 motherboard together with an LSI Logic FW533 or an FW643 1394 host controller. The computer crashes in the following situations:
  • After you disable and then enable the 1394 host controller
  • After you uninstall and then install the 1394 host controller
  • When you perform a clean install of Windows 7 or Windows Server 2008 R2 and then restart the computer a second time
  • After you wake the computer from sleep
For example, you may encounter this issue when you use an nVidia MCP7A-GeForce 9300 rev B1 motherboard together with an LSI Logic FW533 or an FW643 1394 Host controller.

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 when the computer enters a low power (D3) state. When the 1394 host controller later enters a high power (D0) state, it may generate an incorrect PCI-Express packet. In this situation, the motherboard chipset stops responding.

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