I'm on gingerbread now. I did the same steps to enable the support of ext4 but I got the same errors. I noticed that I didn't post the dmesg output. Here is what is logged <6>yaffs: dev is 32505856 name is "mtdblock0" <6>yaffs: passed flags "" <4>yaffs: Attempting MTD mount on 31.0, "mtdblock0" <4>yaffs_read_super: isCheckpointed 0 <4>save exit: isCheckpointed 0 <4>goldfish_nand_read: invalid read, start 400, len 200, dev_size 4000000, write_size 800 <3>end_request: I/O error, dev mtdblock1, sector 2 <3>EXT4-fs: unable to read superblock <6>yaffs: dev is 32505858 name is "mtdblock2" <6>yaffs: passed flags "" <4>yaffs: Attempting MTD mount on 31.2, "mtdblock2" <4>yaffs_read_super: isCheckpointed 0 There is an error when the system tries to mount /data. Do you think that it is due to system.img and/or ramdisk.img? Maybe they are meant to be used with yaffs2.
