Re: suspend to disk unreliable?
I do not exactly know your problem but suspend and hibernate are not always
exclusive things. Some configuration puts system into suspend to memory while
having the same data stored into harddisk too. So you win in both boot time
and complete battery drain situation.
see uswsusp package.
Description: tools to use userspace software suspend provided by Linux
This package (also known as µswsusp or simply suspend) contains the programs to
use the userspace software suspend facility available in Linux kernels
2.6.17-rc1 and higher. It allows the system to have its state saved to disk and
be powered off. On restarting, it will be put back in the state it was left in
(this is sometimes called hibernation).
It also includes a program to suspend the system to RAM after the state is
saved to disk. In that state, the system still uses power, but resuming is
faster. If the battery depletes, the state is resumed from disk without data
Optional features include encrypting the system snapshot and a themeable splash
screen during the suspend and resume processes.
To use this package you need a Linux kernel version 2.6.17-rc1 or newer
configured to use an initramfs. Hooks and scripts to integrate with
initramfs-tools are provided.
