The new version of e2fsprogs, 1.43, adds a new filesystem feature, metadata_csum, which requires Linux 3.6+. We only have 3.0.101 for i9300 so mounting the root filesystem fails with:
EXT4-fs (loop2): couldn't mount RDWR because of unsupported optional features (400) We add a new option to the image creation's mkfs.ext4 command to disable metadata_csum.
