Suspend2 allows you to hibernate your machine without needing APM, BIOS, or ACPI support.
Suspend2 creates an image that is saved in your active swap partitions, swap files, ordinary files or (soon) across a network.
At the next system boot, the kernel detects the saved image, restores the memory from it and then it continues to run as if you'd never powered down.
What's New in This Release:
· Since 2.2-rc12, there have been further bug fixes and a few enhancements.
· The software is now in feature freeze, getting prepared for seeking to merge into the vanilla kernel.
