[Bug 55535] Hibernation fails after changing of the Swap Space

[Raghavendra Nayak]

Public bug reported:

Hi... I recently upgraded RAM of my comp. from 256MB to 768MB.Same time
I added one more swap space of 940 MB to the system and removed old swap
space of size 540 MB from the system.

Since then I'm unable to hibernate my system. When I click on hibernate
button my computer monitor turns off, but after a little while
everything returns to its original state..

When I press Control+Alt+F12 I see following Error Message there.

[4303591.664000] swsusp: Can not find swap device, try swapon -a

I tried command sudo  swapon -a, But same thing continues.

If I manually run the script /etc/acpi/hibernate.sh i get following
error.
