驱动编程，蓝屏问题，求助

编译是过了，但是只要一加载就直接蓝了！DbgPrint("the  DriverEntry !!");这句也没执行到~~也没什么低中断级的函数调用，是在不知道哪里处理处了问题了~~
NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject,PUNICODE_STRING unstr)
{
    NTSTATUS status=STATUS_UNSUCCESSFUL;
    PUNICODE_STRING SymbolicLinkName=NULL;
    PUNICODE_STRING D_Name=NULL;
    PDEVICE_OBJECT DeviceObject=NULL;
    ULONG i;
    DbgPrint("the  DriverEntry !!");
    RtlInitUnicodeString(D_Name,L"\\Device\\K_antive");
    RtlInitUnicodeString(SymbolicLinkName,L"\\DosDevices\\A_safe");
    DbgPrint("the device is prepare creat !!");
    for(i=0;i<IRP_MJ_MAXIMUM_FUNCTION;++i)
    {
        DriverObject->MajorFunction[i]=mydispatch;
    }
    DriverObject->DriverUnload=Antive_unload;
    status=IoCreateDevice(DriverObject,0,D_Name,
        FILE_DEVICE_UNKNOWN,
        0,
        FALSE,
        &DeviceObject);
    if(status!=STATUS_SUCCESS)
    {
        DbgPrint("the device is creat fail!!");
        return status;
    }
    DeviceObject->Flags &= ~DO_DEVICE_INITIALIZING;//DeviceObject+1ch Flags
    status=IoCreateSymbolicLink(SymbolicLinkName,D_Name);
    if(status!=STATUS_SUCCESS)
    {
        DbgPrint("the symbolic link is creat fail !!");
        IoDeleteDevice(DeviceObject);
        return status;
    }

    return status;
}
