linux启动不起来，第一次总是这么难受

[armwind]

第一次移植linux（S3C2440），内核引导成功，但是卡在这里，不知道怎么解决，求大神们帮看看可能是哪个地方出现了问题。
内核源码拿过来，我就稍微改了下nand mtd分区，别的没动，可能是驱动参数不对，导致的吗？

看起来可能是“稍微改了下nand mtd分区”造成一些问题。 你是怎么修改的分区啊，体现在系统的启动配置文件里面了么？

是不是内核 bootargs 里边参数init 设置不对Kernel command line: noinitrd root=/dev/mtdblock3 console=ttySAC0 init=c 还是没显示全
