 请帮看看2.6.12.1内核加载yaffs文件系统出现的问题？
我现在正在做把linux 2.6.12.1内核移植到基于s3c2410x处理器的ＡＲＭ板上。
我在板子上已经烧录了bootloader(vivi，可烧录kernel,yaffs根文件系统），
内核2.6.12.1(用arm-linux-gcc 3.4.1编译，并且已经支持yaffs文件系统），以及yaffs映像文件。
我在vivi中用part命令在nand flash上分了四个区，分别是vivi区，param区，kernel区和root区。
这四个分区是和内核的devs.c文件的分区信息一一对应。

现在在加载yaffs根文件系统时总是失败
　　提示如下:

　　为什么会出现这种情况？我在vivi下输入的启动参数如下：
　　param set linux_cmd_line "noinitrd root=/dev/mtdblock/3 init=/linuxrc console=ttySAC0"
　　好象是输入的启动参数不对,但不知应该怎么改？
    另外，提示有这样一条信息：IP-Config: Device `eth0' not found.
　　说明网卡驱动不正常，板子的网卡驱动芯片是cs8900a。不知哪位高人有这方面的经验，可以指点小弟一二。
