现象从 svn 仓库check out 一份内核， 然后make (该配置内置了initramfs 文件系统)，第一次make 成功， 但是此后再也不行了！make , make clean 等后都会出错。给开发带来极大麻烦。
内核版本: 2.6.21.5
出错信息如下：

问题解决
(同时打算再仔细研究一下 Makefile 语法:P)
google 了一下， 查到文档:
http://www.ibm.com/developerworks/cn/linux/l-debugmake.html
该文档说make 时使用 -d 参数可以看到大量信息， 试着用 make –d, 最后几行：

看一下，usr/.initramfs_data.cpio.gz.d 为initramfs 的目录列表，
试着删除文件 usr/.initramfs_data.cpio.gz.d 再 Make, 居然不出错了！！！
20081007_kernel>rm -f usr/.initramfs_data.cpio.gz.d
