What status quo ? I've proposed a set of changes that will help fix known and identified issues. I just don't propose to change a whole model that works with one that I know won't work just for the sake of supposedly improving an debuggability problem which isn't even there. Debugging suspend() is easy. Just prevent the console from going to sleep and don't put the machine in S3 at the ned of the process (just go through the device model suspend and reusme right away with a hack to not suspend the console driver and its parents if any). The problems are in resume most of the time and you aren't fixing any of this. On the contrary, you will _introduce_ new problems in suspend in fact if you start going away from the model where suspend has to make sure we stop processing incoming things. And no, switching interrupts won't help. It might be a band-aid but it's certainly not a model, and it's totally useless for runtime PM. > Me, I don't care.

So the whole point of open source is that you know better than everybod who has ever actually worked on the problem & implemented successfully suspend and resume, and thus will break everything for how many monthes/year beyond repair just because you are right and everybody else is wrong ? Go for it, go. Looks like I won't upgrade the kernel on my latpop for a while ... Ben.
