Problem with resume from hibernate

[kubco2]

I have had similar problems with hibernate on several laptops and I have simply stopped using it on those that cause trouble; I alter the power saving settings to just change to blank screen when idle, and alter hibernation to never...

It is not solution because when I am on critical battery, I need hibernate ... no suspend no shut down.

Marky FAQ: what do you mean? ... In windows is no problem with hibernate

Same situation again!

In Windows I set my laptop to hibernate when I close the lid. When I shut the lid it hibernates.

In Ubuntu I set my laptop to hibernate when I close the lid. When I shut the lid it force quits, improperly closing programs, and losing data.

This is a common problem i have seen, I had faced this problem in Ubuntu 10.10 also.
Things when more complicated for me when I upgraded to Ubuntu 11.04. My swap partition got encrypted automatically. My swap was active at boot time but resuming from hibernation always failed.

I have written a blog post on how to solve this problem Go to my blog.

Hope that helps you.

Thank you! I got to step two where I received the response:

swapon failed: Device or resource busy

Post the outputs of the following here

sudo fdisk -l | grep swap

blkid | grep swap
cat /proc/swaps
cat /etc/initramfs-tools/conf.d/resume

[kubco2]

sudo fdisk -l | grep swap
/dev/sda7           77117       77823     5668945   82  Linux swap / Solaris

sudo blkid | grep swap
/dev/sda7: UUID="82d053e6-4b8f-40f5-a8c0-2dc77d863302" TYPE="swap" 

cat /proc/swaps
/dev/sda7                               partition    5668940    29408    -1

cat /etc/initramfs-tools/conf.d/resume 	
RESUME=UUID=82d053e6-4b8f-40f5-a8c0-2dc77d863302

I think all is OK, because sometimes it resume. As I wrote: it is 50% chance to fail resume

I find all your configuration correct. Recheck your configuration when you shut the lid. if everything is fine then
check if your swap is active

cat /proc/swaps

and then
Regenerate your initrd.

sudo update-initramfs -u

Reboot.

Good Luck
