Error message after booting

My board is booting fine but i get an error mesg after sometime of booting. What could be the reason ?
[ 89.898629] blk_update_request: I/O error, dev loop1, sector 0
[ 89.904555] SQUASHFS error: squashfs_read_data failed to read block 0x0
[ 89.913678] squashfs: SQUASHFS error: unable to read squashfs_super_block

It sounds like an error in either storage, or an initrd. You should probably post a full serial console boot log. See:
