I am trying to trouble shoot an issue one of our users is experiencing with their laptop. Essentially they get a MULTIPLE_IRP_COMPLETE_REQUESTS STOP error when resuming the system from sleep mode. Now the obvious workaround is to disable sleep mode and then there will be no more BSOD. The user likes the sleep mode as they travel a lot away with the laptop and are unconvinced about having this disabled long term.

Things I have tried are deleting and reinstalling Kaspersky AV as the AVP.exe from the WinDBG output below made me think it was that to blame. ntkrpamp.exe also pointed me in this direction. Other people on the internet have suggested idle USB drives being to blame but the user is not using these when the crash occurs.

Another point of interest was the debug log suggesting it is usually video drivers. Brilliant, I thought, let's head over to Sony and download them. Unfortunately there are no updated video drivers. Perhaps NVidia has some then? It does but they are not supported for the Sony Vaio laptops. Start again :)

Does anyone have any potential insight in to this issue? Or possibly someone understands WinDBG output much better than I do?



A driver has requested that an IRP be completed (IoCompleteRequest()), but
the packet has already been completed.  This is a tough bug to find because
the easiest case, a driver actually attempted to complete its own packet
twice, is generally not what happened.  Rather, two separate drivers each
believe that they own the packet, and each attempts to complete it.  The
first actually works, and the second fails.  Tracking down which drivers
in the system actually did this is difficult, generally because the trails
of the first driver have been covered by the second.  However, the driver
stack for the current request can be found by examining the DeviceObject
fields in each of the stack locations.

EDIT: In fact looking at the graphics card in more depth I am a touch confused. Sony say it is an NVidia 9300 GS while Device Manager states it is manufactured by NVidia but is Mobile Intel(R) 4 Series Express Chipset Family. Feel like I am losing my marbles. According to this site it may be that I have both graphics cards for power saving functionality. Could anyone that knows more than me about this possibly clarify it?

The notebook is question has hybrid graphics: It has both a 9300GS and an Intel Series 4. There is a little switch to change graphic cards on the top left corner of the laptop. See if the sleep problem occurs in both modes (Stamina or Speed). If it does, I would say your drivers are ok, the problem is somewhere else.

I recommend a BIOS update (if you haven't already done that), and a newer set of drivers (if you it doesn't show any new ones, just try searching for all notebooks from the same series in esupport from Sony, they all should work).

If you pinpoint the graphic card driver as the culprit of your problem, and even the Sony drivers don't work, try finding a "modded driver set" on the NotebookReview forums, or at laptopvideo2go.

oh now that is the kind of detail i was looking for! thanks very much for the pointers, I will look in to your suggestion and see what the outcome is. Thanks again – Tim Alexander Jul 8 '10 at 15:38
seems to be holding up after the BIOS update despite the list of changes only being focussed on the Wireless card. Will assign the bounty once i get the all clear from the user. – Tim Alexander Jul 9 '10 at 10:02

I recommend you to uninstall Kaspersky AV, and install/temporarily use Microsoft Security Essentials. Then test the machine for a while to see if the error occurs again. This way you can make sure if the problem is related to Kaspersky or not.

thanks for that. I have tried wtaniguchi suggestion and so far it seems to be holding. I have returned it to the user for further testing but if it comes back I may well try your suggestion. Thanks again. – Tim Alexander Jul 9 '10 at 10:01
