启动linux系统时出错

版主你好！我重新下载了一下linux内核，下载的还是光盘里的，以前也是这样下载了，没有问题，不过这次下载后启动就出错了
....
yaffs: dev is 32505858 name is "mtdblock2"
yaffs: Attempting MTD mount on 31.2, "mtdblock2"
block 813 is bad
block 1223 is bad
VFS: Mounted root (yaffs filesystem).
mount_devfs_fs(): unable to mount devfs, err: -2
Freeing init memory: 176K
Warning: unable to open an initial console.
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
麻烦帮我看下是什么问题。

格式化，重新烧写
