i personally do not come to this point. i get an error about could not
resume or something like that.
i made several kernels until now, i tried every possible combinations
and tried to get the most minimalistic kernel possible (i hope). i
completely disabled usb and fiwi support. i also tried apm instead of
acpi but it ended with the same results.
i played around with the preemtible kernel and other new improvements of
kernel 2.6 (whether they have something to do with power managment or
not). but i always get the same results.
there is something i really would like to know. why does these things
work that flawlessly in windows but not in linux? does this have
something to do with vendor specific drivers that are only provided in
windows? does windows use other standards than linux?
the problem is that power managment is (at least for me) the most
important things on laptops. linux provides that many advantages that
i'm not willing to switch to windows only because of pm but this is
really a crappy situation.
is there any hope that these things will work in the future or are there
any other possibilities to debug pm or to support the developers in any
way?

greets,
nils
