One could try 2.6.23-rc4 which had a lot of changes in the MMC subsystem, but without mentioning fixing the bug directly. Just add initrd=0x200000+offset,16M as above.

Why don't you use ext2 as filesystem. Cannot Open Root Device Mapper/volgroup-lv_root Huh? U-boot has no problems detecting the SD card containing the kernel but the kernel has problems detecting the SD card and hence fails mounting the rootfs: s3c-sdi s3c2440-sdi: powered down.
I created 2 partitions on my SD card. However, the kernel is unable to mount the root file system. Aug 22, 2002 Posts: 1586 View posts Location: Arendal Norway #3 Posted by eaanon01: Mon. Please Append A Correct Root= Boot Option Redhat If you configure this as a module, the module's filename is mtdblock.o. 得知，这个就是对应的，mtd的块设备的选项，因此，选上，重新编译，就可以加入mtd 块设备的支持了。 也就可以访问上面的/dev/mtdblcok2了。 【后记】 1.经过实际测试发现，rootfs中的/dev/mtdblockN，还是有关系的，其系统访问此mtd块设备，还是会去访问此文件的，/dev/mtdblockN会连接到底层对应的块设备，也就是这样是对的： [[email protected] root]$ls dev/mtd* -l crw-r--- 1 root root 90, 0 2009-11-16 15:06 dev/mtd0 crw-r---
