请教各位高手一个kernel调试的问题

[复制链接]
发表于 2009-11-19 16:55:03 | 显示全部楼层 |阅读模式
我想用kgdb在2.6.16内核下调试自己的module,用了两台虚拟机进行调试。
1. 首先我在开发机上编译了新的2.6.16内核:
make bzImage
make modules
make modules_install
make intall

2. 然后把arch下面的bzImage, 以及System.map,还有通过mkinitrd做出来的initrd.img拷到了调试机上的相应位置

3. 我把开发机2.6.16内核源码目录下面所有的.ko文件拷到了一个/mod目录下。

4. 调试机用新编译的内核启动,然后在开发机上执行
#gdb vmlinux
(gdb) set solib-search-path  /mod/
(gdb) set  remote baud 11520
(gdb) target ........
然后控制调试机启动,
可是在进行了一些初始化之后gdb端就开始显示很多的new threads,这些thread好像是在read 各个module的symbols,但是一直创建了几百个都没有进入完成启动:

以下是(gdb)在所控制调试机器启动之后所显示的部分内容:
