DRIVER_POWER_STATE_FAILURE蓝屏问题分析

最近有网友新组装的电脑比较稳定的出现DRIVER_POWER_STATE_FAILURE蓝屏，尝试了网上许多的办法都没有解决，请求帮忙分析一下转储文件，本文记录一下整体的分析过程。

1. 问题背景

电脑比较有规律的出现蓝屏问题，如下：

4: kd> !targetinfo
Windows 10 Built by: 22000.1.amd64fre.co_release.210604-1628, 
Kernel debug session

这里我们可以发现，系统运行6分钟25秒的时候出现崩溃（据反馈，开机大致7分钟出现蓝屏），和现象基本一致。蓝屏代码如下：

DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.
Arguments:
Arg1: 0000000000000003, A device object has been blocking an Irp for too long a time
Arg2: ffff808f2bd19360, Physical Device Object of the stack
Arg3: ffffd501e185f090, nt!TRIAGE_9F_POWER on Win7 and higher, otherwise the Functional Device Object of the stack
Arg4: ffff808f2bc13970, The blocked IRP

DRIVER_POWER_STATE_FAILURE表示是电源状态错误（在指定时间内没有处理完成电源IRP请求出现蓝屏），蓝屏堆栈如下：

2. 技术概要

通常，为了给一个设备发送电源相关的IRP，都是通过PoRequestPowerIrp来完成的，这个函数的声明如下：

NTSTATUS PoRequestPowerIrp(PDEVICE_OBJECT          DeviceObject,UCHAR                   MinorFunction,POWER_STATE             PowerState,PREQUEST_POWER_COMPLETE CompletionFunction,__drv_aliasesMem PVOID  Context,PIRP                    *Irp
);

在Win10系统下面，PoRequestPowerIrp这个函数的实现大致如下：

调用PopAllocateIrp来创建一个IRP对象，并将完成历程设置为PopRequestCompletion
调用PopQueueQuerySetIrp来完成一个查询或者设置电源请求的IRP。

对于PopQueueQuerySetIrp的实现可以总结为如下：

调用PopEnableIrpWatchdog给IRP设置一个看门狗定时器。
调用IofCallDriver来完成IRP。

2.1 PopEnableIrpWatchdog

PopEnableIrpWatchdog这个函数的流程大致可以总结为如下：

通过PopComputeWatchdogTimeout计算出看门狗的超时时间。
然后初始化一个DPC，并设置好定时器。
DPC的回调例程是PopIrpWatchdog.

2.1.1 PopComputeWatchdogTimeout

PopComputeWatchdogTimeout是获取的如下两个值中的一个：

PopWatchdogSleepTimeout。
PopWatchdogResumeTimeout。

这两个值的结果如下：

4: kd> dd nt!PopWatchdogSleepTimeout L1
fffff801`4c105078  0000012c
4: kd> dd nt!PopWatchdogResumeTimeout L1
fffff801`4c105150  00000078

这里PopWatchdogSleepTimeout是300秒，跟我们开机7分钟之后蓝屏比较接近（也就是说，这个IRP大致是开机后2分钟之内发起的）。

2.1.2 PopIrpWatchdog

PopIrpWatchdog这个是看门狗定时器的回调例程，这个函数大致实现如下：

void __thiscall __noreturn PopIrpWatchdogBugcheck(_DWORD *this, int a2)
{//...TriagePower.IrpList = (_LIST_ENTRY *)&PopIrpList;TriagePower.Signature = 0x8000u;TriagePower.Revision = 2;TriagePower.DelayedWorkQueue = (_TRIAGE_EX_WORK_QUEUE *)ExWorkerQueue;TriagePower.DelayedIoWorkQueue = (_TRIAGE_EX_WORK_QUEUE *)IoWorkerQueue;TriagePower.ThreadList = (_LIST_ENTRY *)&PopIrpThreadList;KeBugCheckEx(0x9Fu, 3u, DeviceObject, &TriagePower, Irp);
}

在这个超时回调函数中，回调用KeBugCheckEx(0x9Fu, 3u, DeviceObject, &TriagePower, Irp);来使得系统强制蓝屏。

2.2 IofCallDriver

在电源IRP中，IofCallDriver函数里面使用PoHandleIrp来处理IRP的调用，PoHandleIrp这个函数使用PopDispatchQuerySetIrp来分发函数。

在PopDispatchQuerySetIrp实现两个东西：

将IRP挂入PopIrpWorkerList队列中。
使用KeReleaseSemaphore(&PopIrpWorkerSemaphore, 0, 1, 0)通知PopIrpWorker来处理。

2.3 PopIrpWorker

PopIrpWorker这个worker是用来处理电源请求的线程，这个线程的线程栈如下：

4: kd> k*** Stack trace for last set context - .thread/.cxr resets it# Child-SP          RetAddr           Call Site
00 ffffd501`e1817060 fffff801`4b7324a7 nt!KiSwapContext+0x76

02 ffffd501`e1817280 fffff801`4b72e274 nt!KiCommitThreadWait+0x159

06 ffffd501`e1817500 00000000`00000000 nt!KiStartSystemThread+0x34

在这个线程中等待PopIrpWorkerSemaphore信号，然后从PopIrpWorkerList去取出IRP执行，我们可以看一下整个Worker的响应线程调用栈，如下：

2.4 总结

综上，我们总结一下PoRequestPowerIrp发起电源IRP的整个过程。

创建一个IRP。
设置好IRP对应的DPC定时器看门狗，如果看门狗超时，那么就会直接蓝屏。
将IRP放入到PopIrpWorkerList队列中，提交给PopIrpWorker来处理。
PopIrpWorker从队列中取出IRP，然后发送IRP到指定的设备栈。

这里我们可以推测的两种情况：

IRP正常完成，那么取消DPC的看门狗。
如果IRP超时，那么DPC定时器相应，然后蓝屏。

3. 问题分析

通过上面分析，我们可以看一下整个分析过程，我们可以初步得出的信息有：

IRP发往的设备对象为ffff808f2bd19360.
蓝屏时候的TRIAGE_9F_POWER结构地址为ffffd501e185f090.
超时的IRP地址为ffff808f2bc13970.

在Windbg中提供了!poaction来解析上述的两个链表(PopIrpList和PopIrpThreadList)，如下：

针对IRP: ffff808f2bc13970 (set/D3,), PDO: ffff808f2bd19360, CURRENT: ffff808f2bcc5d50，我们看看每个设备的电源状态是否设置正常，如下：

4: kd> !podev ffff808f2bd19360

Dope: 00000000:

可以发现每个设备的电源状态为DeviceState=4，看起来似乎是正常的，已经设置成功了，针对这个IRP状态如下：

我们得知IRP_MN_SET_POWERIRP没有完成导致超时蓝屏，这里有两个可疑点：

IRP: ffff808f2bc13970 (set/D3,), PDO: ffff808f2bd19360, CURRENT: ffff808f2bcc5d50：说明这个IRP是将硬件设备设置为D3状态，对于PowerDeviceD3表明是将设备进行关闭的调用，这对于一个存储设备来说是比较可疑的。
IRP_MN_SET_POWERIRP发往哪里进行处理了。

我们先从比较简单的情况来看，看一下IRP在什么地方进行处理了，从!irp ffff808f2bc13970命令大致可以得到，PCI总线已经响应了电源请求处理（也就是说调用了IoCompleteRequest），但是在完成例程中再次对IRP处理的时候失去了响应。

我们对电源处理的Worker和PCI处理的Worker线程进行查看，发现如下：

从上面来看，暂时没有发现相关的异常，因此从IRP来跟踪，难度已经比较大了。不过这里有个比较特殊的点就是Wait Start TickCount 5451 Ticks: 19198 (0:00:04:59.968)，似乎ACPIWorkerThread大致已经等了5分钟，这和我们发起的IRP_MN_SET_POWER超时时间基本一致，但是这也并不能说明什么。

接下来我们看一下IRP对应设备栈的状态，大致如下：

这里有一个非常奇怪的地方就是State = DeviceNodeStopped (0x30a)，设备的状态已经处于Stop状态了，看起来这个状态是异常的，因为一个设备处于工作状态应该是State = DeviceNodeStarted (0x308)，但是缺少信息继续深入下去了。

我们看一下整个系统有没有处于异常情况的操作状态，结果发现如下：

这个操作看起来也比较奇怪（dxgkrnl!DpiFdoHandleRemoveDevice），因为显卡设备一般来说都不会拔除掉（并且这个IRP似乎也没有被底层设备完成了），我们看下显卡设备的状态如下：

4: kd> !DevNode ffff808f2bd04ae0

处于DeviceNodeRemoved状态，显然这个也是有点异常的。

接下来我们看一下所有硬件设备树的状态信息，如下：

4: kd> !devnode 0 1
Dumping IopRootDeviceNode (= 0xffff808f2a7dbaa0)
DevNode 0xffff808f2a7dbaa0 for PDO 0xffff808f2a8cbd50InstancePath is "HTREE\ROOT\0"State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeAwaitingQueuedRemoval (0x30f)DevNode 0xffff808f2a8c6aa0 for PDO 0xffff808f2a8ced70InstancePath is "ROOT\volmgr\0000"ServiceName is "volmgr"State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeAwaitingQueuedRemoval (0x30f)DevNode 0xffff808f2e510ca0 for PDO 0xffff808f2e50cc10InstancePath is "STORAGE\Volume\{29d2189a-7903-11ec-b987-806e6f6e6963}#0000000000200000"ServiceName is "volume"TargetDeviceNotify List - f 0xffffae88c18b0990  b 0xffffae88c4069c90State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeQueryStopped (0x309)DevNode 0xffff808f2e514ca0 for PDO 0xffff808f2e50d8f0InstancePath is "STORAGE\Volume\{29d2189a-7903-11ec-b987-806e6f6e6963}#0000000012E00000"ServiceName is "volume"State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeQueryStopped (0x309)DevNode 0xffff808f2e515ca0 for PDO 0xffff808f2e5108f0InstancePath is "STORAGE\Volume\{29d2189a-7903-11ec-b987-806e6f6e6963}#000000001AE00000"ServiceName is "volume"TargetDeviceNotify List - f 0xffffae88c18b0910  b 0xffffae88c4069090State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeQueryStopped (0x309)DevNode 0xffff808f2e5478a0 for PDO 0xffff808f2e5148f0InstancePath is "STORAGE\Volume\{29d2189a-7903-11ec-b987-806e6f6e6963}#00000013EEF00000"ServiceName is "volume"TargetDeviceNotify List - f 0xffffae88c1859690  b 0xffffae88c4069c10State = DeviceNodeStopped (0x30a)Previous State = DeviceNodeQueryStopped (0x309)

竟然发现整个设备树的设备都是DeviceNodeStopped状态，是什么情况导致的呢？还未可知。

分析进行到这一步似乎在继续下去已经比较困难了，是否这里可以做一个相关猜想：由于硬件的异常，导致设备都处于Stopped状态了，这样硬件设备对于默认IRP的处理就出现问题，例如IRP_MN_SET_POWER，导致IRP处理超时蓝屏。但这仅仅是一个猜想，真实原因是否这样也不可知。

当然这个问题后续的方法可以通过动态调试，从开机开始观察整个系统和硬件设备的状态，来更进一步确认原因；由于现场环境的缺失（并且网友后面通过多次重装系统解决了），并且本人对于硬件驱动的了解也不是特别深入（上述设备的状态是否异常，已经是否有跟进一步的信息确认），本次分析就到这里了。

4. 总结

我们先来看一个问题，据反馈系统大致运行7分钟之后出现蓝屏，为什么会是这个时间呢？因为下面这个超时时间：

4: kd> dd nt!PopWatchdogSleepTimeout L1
fffff801`4c105078  0000012c
4: kd> ? 0000012c
Evaluate expression: 300 = 00000000`0000012c

300秒刚好是5分钟，估计这个IRP应该是在开机大致2分钟上下的时间产生的，因此也就导致系统在7分钟的时间出现蓝屏。

综上，上述问题的产生似乎并非软件引起，那么是否是硬件上面的不兼容呢（组装硬件的兼容性问题）？看起来比较大概率是的，但是没有最终的结论。

很遗憾，这个问题花了我周末一天的时间，依旧没有找到具体的根因？如果有网友看到本文章，有思路和建议欢迎留言给出。

5. 附录

这个问题网友后面通过重装了多次操作系统然后解决了，让其帮忙取一下正常情况的转储文件，发现设备状态如下：

0: kd> !devnode 0 1

这个设备状态依旧是State = DeviceNodeStopped (0x30a)，但是系统仍然可以正常使用；看起来似乎挺奇怪的，但也先到此为止吧！
