高手诊断：2.6内核移植启动到Freeing init memory: 96K，就卡壳啦！

高手们，请帮我诊断下,我现在在移植2.6.18的内核到ARM + s3c2410的平台上面来，参考高手们的移植经验，有关nandflash的分区信息我已经添加进去了！并且能够识别nandflash，但是不能进入控制台，启动信息如下：

文件系统的问题吧。可能是/dev下没有设备，也可能是init有问题

我的/dev 目录下面已经创建了console ， null ，如下：

crwxrwxrwx 1 jerry gpu   5,   1 Aug 16  2007 console

crwxrwxrwx 1 jerry gpu 204,   5 Aug 16  2007 ttyAM0

crwxrwxrwx 1 jerry gpu   1,   3 Aug 16  2007 null

内核里面也配置了devfs啊？ 我的启动参数把init=/linuxrc去掉了，还有我这个文件系统在2.4的下面是可以用的！不知道哪里除了问题？请各位指教下！谢谢！

你干嘛要去掉init=/linuxrc？？？

Roemer

内核已经起来了，初始化脚本init的问题~

贴出 目标板 /etc 下的inittab 看看
