Is power management working for CONFIG_KEYBOARD_GPIO? camera and unlock button GPIOs seem to break the powermanagement, too. I disabled it for now. Next hint I got from Sebastian was that I may need to enable power management in /sys. pavel@n900:/my/tui/ofone$ cat /sys/devices/platform/68000000.ocp/48058000.ssi-controller/power/runtime_status active pavel@n900:/my/tui/ofone$ cat /sys/devices/platform/68000000.ocp/48058000.ssi-controller/power/autosuspend_delay_ms cat: /sys/devices/platform/68000000.ocp/48058000.ssi-controller/power/autosuspend_delay_ms: Input/output error root@n900:/my/tui/ofone# cat /sys/devices/platform/68000000.ocp/48058000.ssi-controller/power/control auto I could not get it to sleep :-(.
