    I capture the occasional error with Windbg.

    My driver is a BDA driver + usb driver, when I pass system irp
    IRP_MJ_PNP: IRP_MN_QUERY_INTERFACE to lower layer,
    this error happen:
    *** Fatal System Error: 0x0000007e
    (0xC0000005,0xF816E4D9,0xF897CBDC,0xF897C8D8)
    Help!

    My wrong case:

    USBDriverEntry begins
    USBDriverEntry ends
    RTUsb_AddDevice - begins
    RTUsb_AddDevice - ends
    *** Fatal System Error: 0x0000007e
    (0xC0000005,0xF816E4D9,0xF897CBDC,0xF897C8D8)
    RTUsb_DispatchPnP .......... begin
    RTUsb_DispatchPnP::IRP_MN_QUERY_INTERFACE
    RTUsb_DispatchPnP .......... Use System default process
    RTUsb_DispatchPnP .......... end
    Break instruction exception - code 80000003 (first chance)

    A fatal system error has occurred.
    Debugger entered on first try; Bugcheck callbacks have not been
    invoked.
