Your image does boot for me - after changing features on
filesystem.

	http://dev.laptop.org/~quozl/y/1gHh5m.txt (dmesg)

dumpe2fs of your image filesystem features; has_journal ext_attr
resize_inode dir_index filetype flex_bg sparse_super large_file
huge_file dir_nlink extra_isize metadata_csum, and flags;
signed_directory_hash.

dumpe2fs of my image filesystem features; has_journal ext_attr
resize_inode dir_index filetype extent flex_bg sparse_super uninit_bg
dir_nlink extra_isize, and flags; unsigned_directory_hash.

Our OLPC OS builder uses "mkfs.ext4 -O dir_index,^huge_file", from
e2fsprogs 1.42.5.

I'll look at the microSD card errors; by trying another one.

Fantastic progress though, thanks!  Wish I were a full time kernel
developer, but so much else to do now.

Let me know what you need there; with a patch, and if it isn't too
extensive I could spin a new build.  We're not producing these models,
so I don't _have_ to keep the factory test code working.
