drivers/rtc/hctosys.c: unable to open rtc device (rtc0)
RAMDISK: ext2 filesystem found at block 0
RAMDISK: Loading 2048KiB into ram disk... done.
VFS: Mounted root (ext2 filesystem).
List of all partitions:
1f00 128 mtdblock0 (driver?)
1f01 896 mtdblock1 (driver?)
1f02 3072 mtdblock2 (driver?)
1f03 40960 mtdblock3 (driver?)
1f04 20480 mtdblock4 (driver?)
No filesystem could mount root, tried:ext3 ext2 cramfs msdos vfat romfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(31,3) 两个解决办法：
1 把root=/dev/mtdblock3 改为 root=/dev/ram0
2. 或者把initrd的镜像文件导入mtdblock3
