Description Nicholas Hockey 2007-02-15 19:20:04 UTC

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 believe 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
hw.acpi.power_button_state: S5
hw.acpi.sleep_button_state: S5

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.
How-To-Repeat: Set hw.acpi.sleep_button_state to S1
use sysctrl -s 5 to suspend

Umm, S5 is system-off, not suspend.

Occasionaly i still have a problem with on resume, but i bealive it's
more closely related to acpi. This problem seems fixed in the most
recent snapshot of RELENG_6. When i have more info as to the acpi lock,
i will open a seperate ticket.
