Kernel panic - not syncing: Attempted to kill init!

[daschina]

android平台，想把ubuntu 12.04 跑上去

用官网上的img解压出来的LINUX文件夹里面的文件，复制到SD卡，可以启动到串口login
但是用debootstrap制作的系统不行，报标题的错误

kernel是从uboot启动的，mkbotimg打包了initramfs，initramfs是用busybox做的，init贴在这里
http://paste.ubuntu.com/7788868/

bootargs参数里面有init=/sbin/init

但是debootstrap制作的/sbin/init和官网img解压出来的MD5一样
其他没什么好怀疑的，请问我如何debug，找出死在哪一步了？

检查一下工具链和UCLIBC。
