resume from suspend and hibernation doesn't work, machine powers off and does normal boot instead

[Lord Nelloz]

on my new acer travelmate 8471 timeline with intel chipset (sth with GS4...) when trying to suspend or hibernate, everything seems to work BUT when trying to resume, machine switches off and does normal boot. well, on the acer splash screen the possibilities to press F2 or F12 are missing. everything else works fine. thx for reading and good luck :-)

this is a duplicate of this one: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/405120.
but i'm wondering if hibernation is not working, i own also a TM8471 and suspend isn't working, hibernation does.

Are you sure hibernation (suspend to disk, takes about 30 seconds or more) doesn't work?

It works out of the box for me and many other people (3810t). Suspend to RAM doesn't work.

If hibernation doesn't work for you, it could be a different bug.

thx for answering. unfortunately i am sure, i just tested it again. did
you compare the hardware details with yours? when powering on after
hibernation, some messages appear on the bootscreen but too quick to
read. i have got these encrypted home and swap partitions offered at
installation time.

do you have enabled ahci in your bios?
if so. try to switch to ide, but you can't boot your windows system if you have dualboot.

Hi,

the encrypted swap partition is at fault. You see, when the system is
started, that partition is encrypted with a random key; that key is
thrown away when the system powers down (or hibernates). So, when you
suspend to disk, it writes everything into the encrypted swap partition,
but then shuts down and forgets the key. So when you try to resume, it
can't decrypt the image.
So, long short story, setup unencrypted swap or encrypted swap with a
static key.

Well thank you! Seems to be another bug. Now I set up an unencrypted
swap et voila... suspend to disk now works perfectly. Do I have to
change something in the original bug description?
