usb设备驱动导致蓝屏

版主及各路高手们，我利用winddk下的bulkusb例程进行修改，开发wdm下的usb驱动，遇到了问题，纠结了很多天，希望能够获得大家的指点。
    之前做过一个东西直接用的该例程，在应用程序中进行writefile和readfile没有任何问题。先在需要利用DeviceIoControl来进行通信，采用Method_Direct_OUT方式。为了快速达到能够应用的目的，我将writefile和
readfile中的派遣例程中的代码直接拷贝到deviceiocontrol的相关派遣例程中，并做适当修改，用一个局部变量选择进行读操作或者写操作。
       编译通过,安装并用应用程序对其进行deviceIoControl方式读写后，电脑果断蓝屏，用DebugMonitor查看打印信息发现设备驱动程序执行流程正常，后来我用windbg和在虚拟机中安装xp进行调试，单步执行后，本身驱动
的源代码全部执行完后，再执行几步虚拟机崩溃，查看dump文件发现是在一个地址上进行了读操作导致系统崩溃，发起读操作的是底层的驱动，在DISPATCH_LEVEL的中断请求级上对分页内存进行访问导致系统崩溃。以下是调试信息

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high.  This is usually
caused by drivers using improper addresses.
If kernel debugger is available get stack backtrace.
Arguments:
Arg1: 00000004, memory referenced
Arg2: 00000002, IRQL
Arg3: 00000000, value 0 = read operation, 1 = write operation
Arg4: f827850a, address which referenced memory

我如何具体定位到源代码中的错误呢？在驱动程序中定义一个比较大的全局数组是否不安全？这种方法本身是否可行？谢谢大家。

在张帆的windows驱动开发技术详解中，最后也提到了winddk下的例子，张帆兄能不能指点下是哪里出了问题呢？

原谅我自己顶下
