There are 3 methods: shutdown: save state in linux, then tell bios to powerdown platform: save state in linux, then tell bios to powerdown and blink "suspended led" firmware: tell bios to save state itself "platform" is actually right thing to do, but "shutdown" is most reliable. Old code always did "shutdown". New code does "shutdown", "platform" or "firmware" depending on what BIOS can do. > If not, then what? > > If so, then why do we feel this change is needed, and why did Pat change things? > > My major concern here is that Pat may have made that change to get suitable > coverage testing for new code paths, and we wouldn't want to undo that right away. I believe "platform" is so unreliable (for now) that it blocks usefull testing... I'd like it to default to "shutdown" when it is merged upstream.
