I get:
EXT3-fs (mmcblk0): error: couldn't mount because of unsupported optional
features (40)
EXT2-fs (mmcblk0): error: couldn't mount because of unsupported optional
features (40)
EXT4-fs (mmcblk0): bad geometry: block count 6593 exceeds size of device (6400
blocks)
List of all partitions:
1f00 131072 mtdblock0 (driver?)
b300 6400 mmcblk0 driver: mmcblk
No filesystem could mount root, tried: ext3 ext2 ext4 cramfs squashfs vfat
When using a 3.18 kernel, running under Qemu. I'm attaching the filesystem
image.

--- Comment #1 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com> 2015-01-10 21:34:17 UTC ---
Turned out to be a Qemu emulation issue: my version of Qemu does not align up
the size of the block device emulated, but aligns it down, compared to the size
of the filesystem image being passed.
For example, when forcing the size of the filesystem image to 8192 blocks,
everything is fine. When using 8193 blocks, mounting fails with:
bad geometry: block count 8193 exceeds size of device (8192 blocks).
Closing the bug.
