s3c2410移植linux2.6问题

kylezk

现在在s3c2410上移植u-boot，linux2.6都完成了，网卡也可以用了，用nfs做根文件系统是可以启动的，就是挂载cramfs的时候怎么也不行，下面是log，大侠们帮忙看看啊

incorrect data check
Failed to execute /linuxrc.  Attempting defaults...
try /sbin/init
try /etc/init
try /bin/init
try /bin/sh
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
其中incorrect data check是在fs/cramfs/uncompress.c中增加的zlib解压时的错误信息;
其中的try几句是我在init/main.c中增加的打印语句，
从log来看，好像cramfs已经挂载了，但是linuxrc一直都执行不了，linuxrc用脚本试过，也用busybox链接试过，都一样。
大侠们帮忙啊
