As the kernel doesn't know which FS your root is, it tries the whole list of filesystems
(init/do_mounts.c mount_block_root()). Since the removal of ext3, now the ext4 code is responsbile
for mounting ext3. Since your FS is ext4 and not ext3, the probe for ext3 fails. That's what the
message tells you. You get these even in previous kernels if you say N to ext3 during config.
If it bugs you, you can add a hint to your kernel command line: rootfstype=ext4
