AFAIK, module loading/unloading isn't related to PID at all. Hence I don't think udev should be the problem. What does confuse me is that if it really has to be unloaded then how does it allow on my notebook. > (I should clarify that I am concentrating on suspend-to-ram only; I have > had some success with suspend-to-disk but it takes longer than a reboot and > scrambles the modules; I'm sure they can be unscrambled with a script, but > I don't think I would use it at that speed!) > Amazing that it takes more time :-) > >[...] KDE's klaptop daemon is quite enough to > >handle all my acpi/power related issues.
