I don't think that's necessarily the problem (the modules). I have 2.6.17.13-generic installed with the modules and the initrd set up per the README and I get this message during boot also (on my root partition which is ext3).
lsmod reveals (among other things):
Code:
ext3 120200 0
jbd 46356 1 ext3
I haven't worried about it too much as the system seems functional, but it's clearly a little goofy.
