I'm not sure I understand the last part of this paragraph. Also, users that have mounted storage need to unmount the storage as well. Users of ppp need to shutdown ppp before turning off the power. This does make simple zzz much harder to do, but even apmd can now deal with those issues. : Okay, default mode of PCIC is IRQ mode in coming 4.0-RELEASE, but : polling mode works as well. Actually, I think I like the idea of using polling by default. I think that having it on by default will allow more users to install where eject isn't an issue, but picking the wrong IRQ is a big issue.
