If you set the powerdown method to 0, it will use machine_power_off() instead of trying to use acpi, fall back to machine_halt() if that fails and lastly (should not be needed) a while(1) cpu_relax() loop. > AFAIR the problem with suspend2 was that it didn't poweroff some parts > of the laptop (the led of the wifi pcmcia card was on, and the lcd light > was on too), but that was last year.

The code to poweroff those parts will be dependent on the drivers (assuming I'm making the right calls). If it's something where swsusp works and suspend2 doesn't, it will be because I'm doing something wrong. If they both don't do the right thing, then it's probably the driver. > Honestly, I like this laptop when it works flawlessly, so I don't see > many reasons to try *susp* again.
