jojolin

如题

   这个ramdisk在2.4.18上已经正常启动

  启动信息如下:

经过我重新制作ramdisk 现在启动信息最后显示

[21474652.015000] Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

我认为ramdisk已经加载成功,知识文件系统不正确,应该是init入口的错误,可是我的启动参数有加init=/linuxrc,而且linuxrc中有echo "mount /etc as ramfs"这样的打印信息也没有打印出来,请问这是为什么呢,/linuxrc没找到吗?那应该怎么找呢?
