I confirmed that adding "-E stride=128,stripe_width=512" to the call to mkfs results gets the following errors almost immediately at boot with 3.13.0-157.207:
[ 5.680480] EXT4-fs error (device xvda1): ext4_validate_block_bitmap:376: comm mountall: bg 213: block 7007360: invalid block bitmap [ 5.681182] Aborting journal on device xvda1-8.

It does *not* happen with ext4 and "-E stride=128,stripe_width=512" being set.
