SubjectWhy is 2.6.12.2 less stable on my laptop than 2.6.10?
Date
I know this is a broken record, but the development process within the LKML 
isn't resulting in more stable and better code. Some process change could be
a good thing.

Why does my alps mouse pad have to stop working every time I test a new
"STABLE" kernel?

Why does swsup have to start hanging on shut and startup down randomly?

I rolled back my home box with 2.6.10 because I want some stability (2.6.10
has problems with swsusp from time to time, but it livable for me, for now.)

The process is broken if on a stable series we cannot at least make sure
obvious regressions don't smack users between the eyes.

I see the problem as that too much code flux is happening from people without
the resources, or discipline, to effectively regresion test for side effects
of their changes.

I know there is a lot of back patting on how well the dot-dot stability
release process is working, but that process is a solution for a different
and simpler problem and we still have breakage.

Stability and deliberate feature design and development along with disciplined
regression testing and validation is what is needed. Why can't there be more
targeted and planned development? Are we in a race to see how many changes
we can push into a "stable" tree?

Shouldn't changes be regression tested, formally, before its allowed to go
into a tree?

Why can't I expect SWSusp work better and more reliable from release to
release?

I know there is a point where software goes from fun to work, but without more
deliberate and disciplined WORK I see the 2.6 tree spinning out of control.

The problem is the process, not than the code.
* The issues are too much ad-hock code flux without enough disciplined/formal
regression testing and review.
* Small regressions are accepted and expected to be cached latter.
* ad-hock validation before changes are accepted.

Some possible things that could help:

*Addopt a no-regressions-allowed policy and everthing stops until any
identified regressions (in performance, functionally or stability) is fixed
or the changes are all rolled back. This works really well if in addition
organized pre-flight testing is done before calling a new version number.
You simply cannot rely on ad-hock regression testing and reporting. Its got
too much latency.
* assign validation folks that the developer need to appease before changes
are allowed to be accepted into the tree.
* Make all changes to the kernel not be submitted by the developers, but by
designated subsystem validation owners. If too many bugs continue to sneak
by address the problem by adding validation help to that subsystem or get a
new owner for the problem subsystem. (<-- I like this one a lot.)
* start 2.7
* all of the above (<--this one is good too)

BTW: This may or may not be the opinion of my employer, more likely not.
