OK6410编译好内核2.6.36.2后出现的情况
:handshake 自己修改linux-2.6.36.2的源码移植在OK6410上，运行开发板的情况：（其中UBOOT和根文件系统都是飞凌光盘上提供所对应2.6.36.2的）TCP cubic registered

请问各位大侠这出了什么问题？
先谢谢了！ 楼主应该是修改了飞凌的文件系统。这些报错都是因为修改过rcS文件导致的。 谢谢版主的答复，因为我只是初步学习，UBOOT和FORLINX_6410_touch.cramfs是采用光盘上提供的，内核是在源码网站上下载后自己更改（还没有进行LCD以及DM9000等驱动的移植），才下载到开发板中，就出现这样的提示（当然直接下载光盘中的DEMO文件是没问题），所以我想请教一下这样的情况是不是我内核配置的问题（配置文件是直接复制光盘源码中的.config）？ 使用yaffs2文件系统，就不会有这样的问题了，跟内核关系不大 好的谢谢了我先试试看 我使用yaffs2文件系统出现这样的问题：
