WORKER_THREAD_RETURNED_AT_DATA_IRQL 蓝屏故障，原因何在？

我写的驱动程序功能实现，安装时出现蓝屏！
***stop 0x000000E1(0x80426932,0x00000002,0x00000000,0x80479960)

在DDK中有如下：
Bug Check 0xE1: WORKER_THREAD_RETURNED_AT_BAD_IRQL
The WORKER_THREAD_RETURNED_AT_BAD_IRQL bug check has value 0x000000E1. This signifies that a worker thread completed and returned at IRQL DISPATCH_LEVEL or above.

Parameters
The following parameters are displayed on the blue screen.

Parameter    Description
1            Address of the worker routine
2            IRQL (ought to have been zero)
3            Work item parameter
4            Work item address


Resolving the Problem
To find the guilty driver, use the following kernel debugger command:

kd> ln address

where address is the worker routine address given in Parameter 1.

看不懂啊！我怎样才能确定我的程序那里出了问题？

说的很明白了呀80426932为你工作线程地址，...我的msn是：

我怎么知道80426932为那个工作线程？

我的驱动里有向另一个WDM发送自建IRP的代码，会不会是这里我们处理好？但用softice调试这里的代码都好好的，没有异常，反倒是每次都是在调用MiniportSetInformation（Oid为OID_802_3_MULTICAST_LIST）返回（成功）后蓝屏就发生了。

我加了你：）

PCI_OBJECT指针为空

PCI_OBJECT指针为空

PCI_OBJECT 为接受miniport传送数据的WDM指针，是通过IoGetDeviceObjectPointer(&DeviceName,FILE_READ_DATA | FILE_WRITE_DATA,&FileObject,&PCI_OBJECT)取得的，这里在实际测试的时候不会注释掉的。我打印了PCI_OBJECT指针不为空。
我在调试调试

你上msn吧

问题解决了

因为我同步时加锁在NdisAcquireSpinLock（）和NdisReleaseSpinLock（）之间执行了过多的代码。

DDK中有如下：
A driver should never hold a spin lock for an extended period (more than a few instructions). Holding a spin lock for longer than 25 microseconds degrades both system and driver performance :o
