Comment 5 for bug 120310

I noticed my swap partition was not loading after a failed attempt at hibernating so I looked around at some other bugs and found this one: http://launchpad.net/ubuntu/+bug/66637

I was having the same issue with the swap disappearing so I did as suggested in the following quote:
"I had to do the following to solve it:
- correct fstab with the UUID outputted by mkswap (vol_id might work, but /dev/disk/by-uuid definitely don't)
- put "RESUME=UUID=<uuid>" in /etc/initramfs-tools/conf.d resume.
- update-initramfs -u after you have edited /etc/initramfs-tools/conf.d/resume"

After rebooting the splash screen froze so I restarted into recovery mode. When fsck started running I got the "Soft lockup detected on cpu#0" error. I rebooted again into recovery mode which worked (fsck ran fine this time) and created another dmesg log file which I have attached. Hope this helps determine the problem.
