[ros-dev] ACPI status

[Gge]

I built Ros with ACPI=1 but the feature is not working (in real 
hardware) as the computer does not go into low power state .

At boot the debug messages displayed are :

DriverBase for acpi.sys : 9ce1300
Advanced Configuration and Power Interface Bus Driver
ACPI: System firmware supports:
+------------------------------------------------------------
| Sx states: +S0 +S1 -S2 -S3 +S4 +S5
+------------------------------------------------------------

What is the status of the ACPI feature ? Is it supported actually ?

Best regards
Gerard
