You would be able to rollback, through.=20=20 But that's significantly better than any USB problem or any ALSA problem or any ACPI problem bringing down my entire world, which is the current situation with Linux 2.4. I have the impression that the core developers are unaware of the fact of how unstable Linux has become, particularly on laptops. I guess if you do kernel work and reboot often, you never notice that. Besides, doing stability work is "unfashionable"... =2D-J.
