Cannot insert breakpoint

最近在尝试利用kgdb+vmware来调试无线网卡驱动模块

(gdb) add-symbol-file /home/rt73-cvs-2008032505/Module/rt73.ko  3503194112//1 在加载模块前就设置断点

我的问题：我尝试把host端的rt73.ko直接铐到target端并插入 提示：模块格式错误 插不进去
没办法 只好在target端再重新编译 install 加载
于是就出现上面的问题 只要一设置断点 就会不停的报错：Error accessing memory address 0xd0ce8000: 未知的错误 4294967295.

大家帮我看一下 到底该怎么解决 谢谢！！！！！！！
