记录一次Win7蓝屏分析与解决——Windows表示这锅我不背

这是2017年的事了，最近清理硬盘时发现了当时的dmp文件，于是又想起了这次debug的经历。

现象：同事抱怨装有Win7的笔记本总是无缘无故蓝屏，经常是在写文档的过程中蓝屏，没有任何征兆，多的时候每天会出现四五次，已经影响工作了。这种没有征兆的蓝屏本来就是最难处理的一类问题，我本来打算建议同事重装系统，但盯着蓝屏的底部提示memory dump已生成的提示信息，心想不如死马当活马医，搞不定再重装也不迟。于是拿到了附件中的两个文件，其中的dmp文件是mini kernel dump，xml文件是同时生成的系统信息。

在我自己的电脑上用WinDbg通过File菜单->Open Crush Dump打开112217-12495-01.dmp文件，经过几十秒加载符号文件之后，提示如下：

根据这段分析报告中给出的猜测：
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.
很可能是某个驱动程序使用了错误的指针。那么我要找出具体是哪一个驱动程序的锅。继续往下看：
Unable to load image \SystemRoot\system32\DRIVERS\athr.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athr.sys
这一句提示无法加载athr.sys，为什么只有这一个文件提示出错呢？我猜这个文件应该来自第三方，不属于Windows。在下面的“STACK_TEXT”中也可以看到，栈中确实有athr，这几行只显示内存地址，而其他的call frame都是来自ndis、nt、tcpip这些系统组件，跟我的猜测是一致的。追查一下athr.sys这个文件，在WER-43227-0.sysdata.xml中直接搜athr.sys：
<DESCRIPTION>Qualcomm Atheros AR938x Wireless Network Adapter</DESCRIPTION>
<HARDWAREID>PCI\VEN_168C&amp;DEV_0030&amp;SUBSYS_3112168C&amp;REV_01</HARDWAREID>
<SERVICE>athr</SERVICE>
<DRIVER>athr.sys</DRIVER>
根据DESCRIPTION，它是高通无线网卡的驱动。虽然根据以上信息还不能确定一定是它的锅，但至少可以尝试一下最新的版本。按型号在官网上一查，果然已经有了更新版本的驱动。在同事的电脑上安装最新版本之后，蓝屏再也没有出现过。

这次分析与解决蓝屏的过程其实非常简单，我从中学到了下面几点：
1. 并不是所有的蓝屏都是Windows的锅，第三方软件嫌疑也很大；
2. 蓝屏看似可怕，但如果尝试去分析一下，会发现至少有一些蓝屏并不难解决；
3. 如果没有找到原因，仍然用笔记本自带的bug驱动，即使重装系统也未必解决问题。

分析思路不错，我都不知道还有个xml文件，一般都是找到信息点然后上网查一下是什么东西，再找解决方案

那个xml文件名是WER开头的，说明是Windows Error Reporting生成的。如果加入了“Windows体验改进计划”，那么WER会把dmp和xml上传到微软的服务器，微软会有人对故障原因进行分析。如果确实是windows的问题，微软肯定会修复的。如果是驱动的问题，那么微软也能够根据驱动签名联系到生产厂家进行修复。
windows的bug或驱动bug通常不会只有一个人遇到，微软很可能已经修复了。这个帖子里遇到的问题很可能就属于这种情况。

叫我Wait啦

思路学习了~

关键是重装系统后，可能这个网卡驱动是最新版本的，问题也解决了。所以蓝屏还是装系统快一些。

较少使用调试软件，受教了。谢谢。

我倒是不敢随便更新驱动，win10，很容易当机
