in my experience (and I've quite a bit of this:) it's essential to do
small steps. There are 2 types of small steps
1) small steps in your patch
2) small steps in what you move it to


Thanks for the advice, I will make sure to do that in the future.

Even now that you are where you are, I'd suggest going via at least one,
if not two, intermediate steps. Say 2.6.12 and 2.6.15. Make those work
first, test them a lot, and only then go to the next step.

(and going forward, once you are at a current tree, keep up with
mainline *frequently*)


I have looked a little into the changes and how they affect our patch.
I see your point that the move directly to a current kernel will be
very hard and error prone. Unfortunately, I don't have the time right
now to do the move(s) (deadlines...), so I have decided to postpone
the move to a current version a little more and continue development
on the old version. I know that this doesn't help the problem at all,
but I can worry about that after I have met my deadline...

Thank you very much for your advice!
