Currently some people can't suspend with the mainline code because it cannot free as much memory as needed on their boxes. I think we should care for them too. Besides, if they could suspend, we'd have more users and more testing coverage for device drivers, especially for devices that are no longer installed in newer boxes. ;-) Greetings, Rafael - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
