内核崩溃--大虾指教

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0），我重做了，几次都是这个问题，我自己下的源码，我自己做的配置，不过按照移植手册做的，很困惑呀，我还没做文件系统，但是Linux中也应该带有文件系统啊，怎么会文件系统挂载不上呢？困惑啊...

应该不仅仅这个错误提示，这是最终的提示。前面应该还有提示

嗯，前面的提示是drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
VFS: Cannot open root device "mtdblock2" or unknown-block(2,0)
Please append a correct "root=" boot option; here are the available partitions:
0100       4096 ram0 (driver?)
0101       4096 ram1 (driver?)
0102       4096 ram2 (driver?)

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0)

难道是我配置drivers 的问题?
