Hi folks

Is it possible to suspend to disk instead of suspend to ram?

openelec ~ $ cat /proc/acpi/wakeup

USB0 S3 *enabled pci:0000:00:1d.0

suspend to disk is S4, so it is possible?

what i have to do?
is ist possible to have in shutdown menu a button "Suspend to Ram" AND button "Suspend to Disk"

Background:
i have enabled sabnzb and boot times are now to big.
without sabnzb boottimes are 10sec => no reason not to boot:-)
but with sabnzb suspend to disk would be faster then boot

root / # cat /sys/power/state
standby mem

so what i'm missing is "disk"
i have read that we need a swap partition for that..right?

root / # df -h
Filesystem Size Used Available Use% Mounted on
none 499.3M 280.0K 499.0M 0% /dev
/dev/sda1 177.0M 128.8M 48.2M 73% /flash
/dev/sda2 930.4G 33.5G 896.9G 4% /storage
/dev/loop0 115.5M 115.5M 0 100% /
none 501.0M 0 501.0M 0% /dev/shm


what i have to do next?

create a swap partition or can i use /dev/shm ? how do i that..

(i have installed 2GB RAM, so i have to resize it at least?)

thanx for helping

To use suspend to ram you indeed need a swap partiton. But OE is also targeted at installs on USB/SD/SSD, where you don't want swap, and certainly not a big one. Couple that with the fact that OE boots very fast (without sabnzbd) i doubt support for suspend to ram will be a feature, there aren't much use-cases for it.

Using /dev/shm for swap/suspend to disk is useless, since shm is a ramdisk, so you would end up with a suspend to ramdisk, basically the same as suspend to ram

i'm not sure if understand it.

i'm intrested in suspend to DISK.

SAME Machine (zbox ID80, 2GB ram, 1TB HDD)
My winXP-htpc resume from suspend2disk state 2X FASTER! than booting openeelc (clean install, NO sabnzb!).

that's nothing i want to live with

so i would like to setup suspend 2 disk for openelec too..i expect that would be faster than booting openelec!?

so, somebody has done a setup with suspend 2 disk?

why nobody like the suspend2disk feature, also on windows..people like booting, i have never understand why they like to wait, maybe its a "ritual" thing..
