How to stop using Ext3?

I have my fstab set up to mount / ext2. But I get this:

crcarle@mango2:~> cat /proc/mounts
rootfs / rootfs rw 0 0
/dev/root / ext3 rw 0 0


crcarle@mango2:~> mount
/dev/sda2 on / type ext2 (rw,acl,user_xattr)


crcarle@mango2:~> cat /etc/fstab
/dev/sda2 / ext2 acl,user_xattr 0 1
/dev/sda1 swap swap pri=42 0 0

How do I make the system stop mounting / as ext3?

Also, what is the meaning of all this from dmesg:

Thanks for input.
