If this is true, then it's only because the Ubuntu developers do not want to support older kernel versions. Other distros handle this just fine (Gentoo and Debian for example). This is not a kernel issue, but rather a distro design issue. Which is much different from the fact that I take a "ext3" partition from my new distro and can't get to the data if I downgrade to an older distro for whatever reason (or use an older rescue disk.) Don't confuse distro design decisions from issues forced on an unknowing user by the ext3 fs kernel developers. thanks, greg k-h
