"ACPI
The Advanced Configuration and Power Interface (ACPI) has a lot of different functions, most of
which interfere with RT performance (for example: power management, CPU power down, CPU frequency
scaling, etc). The EMC2 kernel (and probably all RTAI-patched kernels) has ACPI disabled.
ACPI also takes care of powering down the system after a shutdown has been started, and that’s
why you need to push the power button to completely turn off your computer."
