This means that your initrd has "ext3" as the root filesystem type in /etc/fstab or similar. If the filesystem type is explicitly given as "ext3" then the ext4 driver will not try to mount it. I suppose it might be reasonable to have a config option that adds the "ext3" and "ext2" filesystem types to the ext4 driver for cases like this where CONFIG_EXT2 and CONFIG_EXT3 (and module equivalents) are disabled.
