20 Yes, it is. Moreover, it is due to the ext3 legacy code that you are
21 getting the EXT3 error (the first one) in /var/log/messages.
22 Even if you remove ext3 legacy support from kernel, the ext2 and ext3
23 filesystems will be handled by the "new" ext4 code.
24 As for the EXT4-fs message, probably it tries to mount the fs as ext2
25 first but it is not quite consistent for different fs, I'm getting it on
26 some but not getting on others.
