PC Shutdown problem with MXI express

[Robert__R]

SajK,

I'm glad to hear the registry keys fix the problem. 

They work by telling the OS that the 2 devices (80860340 and 80860341, which are the device/vendor ID of the 2 ports of the bridge used on MXI-Express) shouldn't be put into D3 hot at shutdown or suspend.  Since the bridge has trouble with this state, avoiding the state fixes the problem.

This doesn't really have any other effects that I'm aware of.  It targets the device and the particular state that has the problem.

Thanks for trying it out.

Hello, I have the same problem here.

Can someone tell me (maybe with a screenshot) where to find the device/vendor ID of the 2 ports of the bridge used on MXI-Express? Is it hex or dec?

thanks

Krausalat,

If you're having the same issue with MXI Express (specifically with the NI PXI-8360) then the same solution should work for you.  If it's a different version then let me know and we can work that out.  Also, adding the keys won't hurt anything even if you don't have MXI Express installed, so there's no harm in trying.

If you want to find the device/vendor ID in Windows XP, open Device Manager.  Select view->by connection, then expand a few things.  In my case it's "ACPI Multiprocessor PC -> Microsoft ACPI-Compliant System -> PCI bus".  That gets you to where there are some bridges.  You should expand them until you find some of the boards in your chassis.  The bridge above that should be MXI Express.

If you double-click the bridge (or right-click and select "properties"), then select the details tab, you'll see a string in the box.  It should say something like "PCI\VEN_8086&DEV_0341...".  The numbers are hex.

Vista is similar.  Let me know if that doesn't get you there or if you're still having issues.
