While gathering the information I found the culprit. The resume file in initramfs config had a different UUID than my actual SWAP. I had recently changed my swap partition, and it seems that the system doesn't update this file automatically.
Nevertheless , after changing the UUID to the correct value, and updating initramfs, it works. Thank you for the help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305137 Title: [LENOVO ThinkPad Edge E430] hibernate/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1305137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
