How is that a copout? The problem was noticed. I am only suggesting
that we not be in such a hurry to put code in the production kernels
until we are pretty sure it works well enough, and that we release
major production versions more often so that they do not contain 2 or
3 years worth of new code making it so hard to debug. We probably
should have had 2 or 3 code freezes and production releases since
2.2.x. As I mentioned in a previous posting, this way we do not have
to run a 2 or 3 year old kernel in order to have reasonable stability.

I am spending a lot of time testing new kernels, reporting bugs and
offering suggestions that I think may improve on the stability of
production kernels. Is this not considered doing something about it?
It is necessary to point out where one sees a problem in order to
offer possible solutions for improvement.
