So anything (UP or SMP) that exercises code paths is helpful. The only SMP-specific things to test are power-off on shutdown. Run it a bunch of times to be sure that it continues to work. Note this isn't in the acpi locking path but ACPI-CA has its own locks which are now not redundantly covered by Giant. It has been running this way in Linux for a year or so. Still, it's good to have that test coverage too. -- Nate
