>Description:
When hw.acpi.sleep_button_state is set to S1 and i suspend my computer using acpiconf -s 5, on resume it freezes. I bealive it's trying to resume from a S1 state even though it was suspended to a S5 state. The reason i bealive this to be true is, when hw.acpi.sleep_button_state is set to S5 everything seems to work fine. Also when when i set either hw.acpi.power_button_state or hw.acpi.lid_switch_state to S5 everything seems to work fine either closing the lid or pressing the power button.
sysctrl hw.acpi output:
hw.acpi.supported_sleep_state: S1 S3 S4 S5

>How-To-Repeat:
Set hw.acpi.sleep_button_state to S1
use sysctrl -s 5 to suspend
>Fix:
if you want to use acpiconf -s to suspend the machine you MUST set hw.acpi.sleep_button_state to the same state prior to issuing the acpiconf command.
