解决办法：

加入linuxrc文件

但是又出现了新的问题：

cannot run '/etc/init.d/rcS': No such file or director

Please press Enter to activate this console.
can't open /dev/tty2: No such file or director

我想问题是出现在linuxrc文件上了，思考中。。。

后来查了一些资料：

问题1, 使用jffs2文件系统:
　　JFFS2 error: (1) jffs2_build_inode_pass1: child dir "fonts" (ino #13) of dir ino #4 appears to be a hard link
　　VFS: Mounted root (jffs2 filesystem).
　　Freeing unused kernel memory: 304k freed
　　Warning: unable to open an initial console.
　　Failed to execute /linuxrc. Attempting defaults...
　　Kernel panic - not syncing: No init found. Try passing init= option to kernel.
　　原因: flash没有erase彻底.
　　问题2, 使用cramfs时出错:
　　VFS: Mounted root (cramfs filesystem) readonly.
　　Freeing unused kernel memory: 304k freed
　　Error -3 while decompressing!
　　804878c4(1884)->81200000(16384)
　　Failed to execute /linuxrc. Attempting defaults...
　　Kernel panic - not syncing: No init found. Try passing init= option to kernel.
　　原因: 没有仔细看 mkfs.cramfs 的手册, 需要指定-b参数, 大小与PAGE_SIZE一样 (查看.config文件 CONFIG_PAGE_SIZE_16KB=y).
　　问题3 :
　　Kernel panic - not syncing: Attempted to kill init!
　　原因: 应该是/etc/fstab 之类的文件没有,重做文件系统后OK
　　问题4, 一直提示找不到/dev/tty2-4, 按下[Enter]后死机:
　　VFS: Mounted root (jffs2 filesystem).
　　Freeing unused kernel memory: 304k freed
　　init started: BusyBox v1.12.1 (2008-10-13 13:37:42 CST)

又要重新编译busybox，郁闷。。。

networking/interface.c:818: error: `ARPHRD_INFINIBAND' undeclared here (not in a function)
networking/interface.c:818: error: initializer element is not constant
networking/interface.c:818: error: (near initialization for `ib_hwtype.type')
make[1]: *** [networking/interface.o] Error 1
make: *** [networking] Error 2

注释掉 820/* .type = ARPHRD_INFINIBAND, */ 就行了。

但愿以后不会出现什么问题吧！呵呵，要去拔河了，回来在做！

领悟中。。。

你的BUSYBOX和你内核的交叉编译工具必需相同

哈哈。。。终于搞定了。自己编写了一个linuxrc文件。添加bash文件到/bin文件下就可以了，一阵英文飘过，心情也变得舒畅起来。。。。。。
