The following patch is somehow causing the issue:
Still investigating further.
[ 3.295677] UBI: auto-attach mtd11
[ 3.295698] UBI: attaching mtd11 to ubi0
[ 3.334563] UBI: EOF marker found, PEBs from 29 will be erased
[ 3.334725] UBI: scanning is finished
[ 3.339293] UBI error: ubi_read_volume_table: the layout volume was not found
[ 3.343386] UBI error: ubi_attach_mtd_dev: failed to attach mtd11, error -22
[ 3.350150] UBI error: ubi_auto_attach: cannot attach mtd11
But with the above patch removed the board will boot when flashed from u-boot.
