           Summary: Invalid ext4 image generated by Buildroot
           Product: buildroot

Using:

BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_EABIHF=y
BR2_ARM_ENABLE_NEON=y
BR2_ARM_FPU_VFPV3D16=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_MDEV=y
BR2_TARGET_GENERIC_GETTY_PORT="ttyAMA0"
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y

BR2_PACKAGE_RPCBIND=y
BR2_TARGET_ROOTFS_EXT2=y
BR2_TARGET_ROOTFS_EXT2_4=y
# BR2_TARGET_ROOTFS_TAR is not set

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.
