Cannot boot device after flashing OS

Built a new image to SD based on toradex instructions

Running run setupdate and run update from the bootloader, the OS cannot boot.

rootfs cannot be mounted.

Serial console log attached

Suggestions on how to recover from this?

We switched to using ext4. Have a look at the following question.

The relevant message to note would have been:

[    7.470220] EXT4-fs (mmcblk0p2): couldn't mount as ext3 due to feature incompatibilities

BTW: You should not be running 2.7.4 being considered an obsolete beta version by now but rather upgrade to 2.7.5 at your earliest convenience.
