E9官方提供的linux文件系统重新压缩后无法运行

我就从光盘里将文件系统rootfs_E9_for_linux_v3.2.tgz拷贝到电脑，然后解压，再重新压缩，没有做任何改动，启动就有问题；如果我直接用光盘里的文件系统的话就没有问题，是解压和压缩的过程哪里出错了？？？

具体打印信息如下：
EXT3-fs (mmcblk0p1): using internal journal
EXT3-fs (mmcblk0p1): recovery complete
EXT3-fs (mmcblk0p1): mounted filesystem with writeback data mode
VFS: Mounted root (ext3 filesystem) on device 179:1.

已经解决，是压缩时的路径问题！
