Depends on how fast. I find it takes a minimum of 3-6 months before any
new kernel release stabilizes (somewhere around 2.6.X-5 to -10), and some
distributions push them out way before that. Also, after major changes,
it can be a year or more before a new kernel is not a regression either in
reliability, performance, or worst-case behavior.
