We also don't enter S4 in the right way, AFAICS, but the infrastructure allowing us to change that is only in -mm. Anyway, here's the patch to fix that (it's on top of some other patches, but the link to them is given in the message): http://lkml.org/lkml/2007/8/7/316 > I wish we loaded the kernel just once, maybe from the boot loader. Well, that's not so easy. That will work for the bare image, but if we want it to be compressed and/or encrypted, then the boot loader will need to contain all of the necessary code. I may be doable by using a special boot kernel with ACPI disabled and only as many drivers as required to load the image, but that will make it more difficult to set up and to recover from errors.
