PC Shutdown problem with MXI express

[SajK]

Hi all,
I am using PXI chassis (PXI 1042) controlled from a Dell Precision 390 Desktop. I am using MXI Express bridge (ie PCIe8360-PXI8360) to controll the PXI chassis. LabVIEW 8.2 is the programming language.
 
On shutting down the Desktop (with PXI chassis  ON), I am getting the following error and System halts there.
 
" *** Hardware malfunction
call your hardware vendor for support.
NMI: parity Check/Memory parity error
*** The system halted ***"
 
How can I overcome the problem?
Kindly suggest.
 
Thanks in advance.

Hi Jason,Thanks for the useful information.
I am shutting down the PC first and then switching off the PXI chassis. Most of the times i am getting this problem(Not always).It is a blue screen.Not a pop up message.
If I am switching off the PXI chassis first and shutting down the system, PC shuts down properly. 
I tested the same with another PC another MXI card (same configuration, Dell Precision 390) , it is working fine.It is not giving any shutdown problem.
I uninstalled the softwares and drivers in first PC and reinstalled it. Even then this shutdown problem exists, in first PC.
Can you tell what could be the problem?

Jason,
 
Both PCs are having the same BIOS version.
I tried the method to get Memory dump file.I feel, it is not getting generated.I could not locate it in C:/WINNT folder.
 
After getting the blue screen with error, PC stays in that state unless power is switched off.

Hi SajK,
What operating system are you using? If you are using XP, this file will be located in the C:/WINDOWS folder. What cards do you have in the PXI chassis? If you remove all of the cards, do you see the same behavior? If you only use one card in the PXI chassis? Can it be narrowed down to a specific PXI card (other than the MXI-Express card) that has to be in the chassis to show this behavior?

Hi Missy,
Following are the system details
Operating system :Windows XP
PC : Dell Precision 390
PXI Chassis - 1042 which presently contains only one card (PXI 8360)
I even tried upgrading BIOS to version 2.2.0. Still the problem persists.
 
If I am Restarting the PC, it is working fine. Where as on giving PC shutdown, PC halts with error. But memory dump file is not generated during Shutdown. I am switching off PC power after getting the error, as the system stays in same state.
If I am starting the PC without connecting MXI cable (with PCIe 8361 installed), it giving the following error. "Error in initializing PCI express slot." Is it normal? If MXI cable is connected and PXI chassis is powered, it is not giving any error during power up.
What could be the problem?
Regards

Hi SajK,

There are two types of blue screens. A software&nbsp;blue screen creates a&nbsp;dump file saying which software caused the problem, and&nbsp;hardware will give a hardware malfunction error. In the case of a hardware blue screen you will not get a dump file. <a href="http://digital.ni.com/public.nsf/websearch/7EEFE03B4517D387862571F0007C161C?OpenDocument" target="_blank">Here</a> is a KnowledgeBase that discusses blue screens with MXI-Express at shut down. I hope this helps!

SajK,

I may have a solution for you.&nbsp; I suspect the problem is with the way Windows prepares devices for shutdown.&nbsp; Please apply this registry key and let me know if it fixes the problem.&nbsp; It won't take effect until after you've rebooted.
&nbsp;
The registry key tells Windows that the device has a problem with the prepare-for-power-down state (D3 hot).&nbsp; Save the file somewhere, then right-click and select "merge".
&nbsp;
If you aren't able to download the file, copy these lines (between the "-----" lines) to a text file with a .reg extension, then merge that file.
&nbsp;

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pci\Parameters]"80860340"=hex:00,00,00,20,00,00,00,00"80860341"=hex:00,00,00,20,00,00,00,00-----
&nbsp;
Thanks.

Robert,
&nbsp;
Great!! :smileyvery-happy:
&nbsp;
It is working fine after adding those 2 registry keys.
Can you tell me how these registry keys solve the problem.
Will it affect anything else (Operating system)?
&nbsp;
Thank you very much.

SajK,
&nbsp;
I'm glad to hear the registry keys fix the problem.&nbsp;
&nbsp;
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.&nbsp; Since the bridge has trouble with this state, avoiding the state fixes the problem.
&nbsp;
This doesn't really have any other effects that I'm aware of.&nbsp; It targets the device and the particular state that has the problem.
&nbsp;
Thanks for trying it out.
