Hibernate

На сегодняшний день в Сизифе поддерживается две технологии засыпания – swsusp в std-smp ядрах и suspend2 в wks-smp, подробно описывать их здесь не вижу смысла.

Для засыпания я использую hibernate, настраивалось все это для ноутбука IBM ThinkPad 570, потом практически без изменений переехало на IBM ThinkPad X24, на котором до сих пор и живет.

Находим swap раздел

# fdisk -l /dev/hda | grep swap

/dev/hda1 * 1 125 1004031 82 Linux swap / Solaris

в /etc/lilo.conf к дефолтному ядру добавляем:

для suspend2

append=" resume2=swap:/dev/hda1"

для swsusp

append=" resume=/dev/hda1"
