I tend to agree with that, it would be great if that were true. well in a way it is, in a way it's not. There is a difference between userspace software and kernel components here. A "broken" userspace app at worst breaks itself. A broken kernel component breaks the entire system, because kernel components have full permission to everything, by definition. (And before you say "then make it not so", you can't do that. Not without getting the same issues that makes people not write userspace drivers today) > Hm well, can't speak for others but the *only* problems I have with the > nVidia drivers are when kernel upgrades break them.

In older kernels, there *also* was only 4K stack space, except that when you used more you could get away with it more (eg as long as you were lucky and didn't get an interrupt during the time you use too much stack, you didn't crash; with the new situation you notice this more frequent). > this time it's apparently udev. the udev thing is 1) not caused by the kernel at all and 2) progress.

It's probably a 5% performance gain or so...
