Minidump Analysis

175 pts.
Blue Screen of Death
Hi all,

I've come across a minidump file that's pretty cryptic, so I'm having a tough time with it. Lately, I've been getting some bsod, and unfortunately the minidumps are pointing more to driver faults within the stack (which makes it difficult to find, for me anyway). If someone wouldn't mind having a look, I'd appreciate it!

Details: ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* MULTIPLE_IRP_COMPLETE_REQUESTS (44) 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.

Thanks. We'll let you know when a new response is added.

Looks like a smartcard reader is causing the problem: oz776.sys Check the computer vendor for updated drivers.

    This is the fault of the power manager who is changing the USB idle state TWICE. A microsoft bug.
