While I have some experience that agrees with this, I'll point out
that I've had the opposite experience, too: upgrading the kernel made
a perfectly stable system both unstable and prone to data loss.  I
think this is a blade that cuts both ways, and the key thing to do is
to ensure you have good testing infrastructure in place to check that
things will work before you deploy to production.  (The other way to
say that, of course, is "Linux is only free if your time is worth
nothing."  Substitute your favourite free software for "Linux", of
course.  ;-) )
