解决Atheros蓝牙导致Windows 7 64位蓝屏

刚安装了Windows7 64位系统，让人痛苦的是新系统以大概每天一次的概率随机发生蓝屏。终于我决定自己找到问题根源。系统在发生问题的时候，会产生.dmp文件。余下的任务就是分析.dmp文件

1. 安装WinDbg 64位

2. 选择网速比较快的时候

3. 用WinDbg打开.dmp文件

输入命令

.sympath SRV*c:\symbols*http://msdl.microsoft.com/download/symbols

含义是下载调试符号文件到本地c:\symbols目录

看看btfilter.sys什么来头

可以看出问题的是btfiler.sys驱动，而这个驱动正是Atheros蓝牙驱动。我找遍了整个网络，只有HP发布补丁解决了这个问题
