What I meant with SUSPEND and/or HIBERNATION was CONFIG_SUSPEND / CONFIG_HIBERNATION. And the relations where from Kconfig: from drivers/acpi/Kconfig: config ACPI_SLEEP bool depends on PM_SLEEP default y -> no PM_SLEEP means no ACPI_SLEEP from kernel/power/Kconfig: config PM_SLEEP bool depends on SUSPEND || HIBERNATION default y -> No SUSPEND and/or HIBERNATION means no PM_SLEEP And if I select SUSPEND and/or HIBERNATION I will not only build this feature into the kernel, but also HOTPLUG_CPU and I want to avoid that. It's exactly as Linus said in his mail: Not everybody wants SUSPEND... I should have formulated that better in my mail, but that was what I wanted to say. Back to debugging this: http://marc.info/?l=linux-acpi&m=119052970904643&w=4 fails to apply against 2.6.23-rc7-mm1, but moving that function by hand was not to difficult. ;) (With only the second patch I got a link error...) http://marc.info/?l=linux-acpi&m=119073173625910&w=4 applied, and a test showed that my system now powers off again.
