windbg调试不能设置断点！

我使用windbg调试文件过滤驱动，目的机器是另外的计算机，其中有这些打印信息出来：
*** WARNING: Unable to verify timestamp for dxg.sys
*** WARNING: Unable to verify timestamp for igxprd32.dll
*** ERROR: Module load completed but symbols could not be loaded for igxprd32.dll
*** WARNING: Unable to verify timestamp for igxpgd32.dll
*** ERROR: Module load completed but symbols could not be loaded for igxpgd32.dll
*** WARNING: Unable to verify timestamp for igxpdv32.DLL
*** ERROR: Module load completed but symbols could not be loaded for igxpdv32.DLL
*** WARNING: Unable to verify timestamp for igxpdx32.DLL

*** WARNING: Unable to verify timestamp for win32k.sys
*** ERROR: Module load completed but symbols could not be loaded for igxpmp32.sys
*** ERROR: Module load completed but symbols could not be loaded for bcm4sbxp.sys，
但是我的驱动中的我自己打印信息也可以出来，但是就是不能在程序中设置断点，请问这是怎么回事啊？？？

先用create+break 中止驱动， 这里F9在源代码里面设，然后 g

要确保两个ｓｙｓ文件是同一个，我之前就遇到过这个问题，我的ｓｙｓ文件不是同一个，Ｗｉｎｄｂｇ没法设置断点
