用vm6.0+windbg调试wdk自带的sioctl驱动。我的wdk是7600版的，编译通过后得到文件，这里生成的pdb有两个，一个是 vc90.pdb，还有sioctl.pdb。把对应的pdb文件放到了自己设置的一个文件夹下（e:\mysymbole）。
kd> .sympath
Symbol search path is: SRV*e:\symbols*http://msdl.microsoft.com/download/symbols
;E:\Mysymbole
Expanded Symbol search path is: srv*e:\symbols*http://msdl.microsoft.com/download/symbols
;e:\mysymbole
WARNING: Whitespace at end of path element
这里面有个warning。百度没有找到什么意思。。。。。我试过把这两个pdb文件放到windbg网上下载的那个文件夹（e:\symbols），但是这样一样不行。
然后连上虚拟机后，我在用.reload命令下载符号文件后，输入：
kd> lm

里面没有我想要加载的sioctl…..

请问为什么会出现这个情况啊？
在原来调试的时候，有些时候能够成功，我是指能够在入口函数处断下来，但是很多次都不能成功。求达人指教。我的pdb文件为什么加载不对啊。。。。。
