[RFC] debug kernel for Lucid/Maverick/Mainline?

Hi all,

I propose we build a kernel with certain XX_DEBUG turned on for Lucid, 
Maverick and Mainline. The benefits of having it are:

* we can point people at this debug kernel give them instructions on how 
to control debug prints though sysfs and get more data that might help 
debug problems. Certainly in the case where debugging kernel across 
suspend/resume etc.

* We could use this kernel in our alpha/beta compatibility testing ISO, we 
could collect more debug information for each test. For example turn on 
debug before suspend and turn off after resume, if suspend/resume had 
issues, took long times etc we might be able to gather bit more 
information as to why.

* I think mainline kernel builds should have config debug turned on by 
default, since this is "try & test this" kernel, what is the harm in 
having a slightly bloated kernel?

Any thoughts?

Cheers
