启动过程如下，感觉主要是最后30行提示出现了问题，就是从"Error -3 while decompressing! "这行开始,到底是什么出了问题呢?

BusyBox v1.7.0 (2009-05-14 22:07:17 CST) built-in shell (ash)
Enter 'help' for a list of built-in commands.

你的网卡驱动有问题阿。。。。

启动的时候不插网线看看看。

如果手上有源码的话，在kernel 里把网卡驱动屏蔽掉。

如果把最后几十行的回溯线索和寄存器上下文看懂了，就找到问题根源了，实在不行去内核社区问问吧

只知道回调线索打印出来的提示：
前面是寄存器，中间是函数线索，后面是偏移量
连起来就看不懂了
