Working through to resolve the hibernation kernel panic issue with a MacBookPro8,2.
All works fine, hibernation seems to function in all cases except - when the machine runs out of battery power. The normal behavior would be that it would go to sleep.
Waking from this state results in a grey screen - backlighting works - nothing else.
Only resolution is to force shut down by holding down the power button.
On restart, enter single user mode (command-s); and executing the following:
fsck -fy
mount -uw /
cd /Volumes
rm -rfv *
reboot
This performs a file system check.
The last commands clear the links to previous disks (mount points) before restarting. They will be re-created. Otherwise, I am seeing duplicate entries, and some applications fail to work properly with the file system.
* Hardware specifics:
- MacBookPro8,2; 16gb ram; OWC Data Doubler with Corsair CSSD-F240GB2 drive as system drive; OSX 10.7.5
* As you need to run down the battery to cause this failure, trouble shooting is tedious.
Observations and attempts to implement suggestions found in the web:

Article describing issues tied to bluetooth.
Suggestion to "Allow Bluetooth Devices To Wake Your Computer. It’s on by default. If you turn that option off (in System Preferences > Bluetooth > Advanced), the system will kernel panic even if you don’t turn off the Bluetooth devices."
If your "Bluetooth" is NOT turned on, this option will be greyed out. You need to first turn ON Bluetooth, to disable click "Advanced", then disable "Allow Bluetooth devices to wake this computer", then turn Bluetooth back off.
Now - I'll wait out the 1hr39min left on my battery before I can check if this actually worked.

Suggestion to: upgrade firmware on SSD drive.
I'm the guy from johnfixesstuff.blogspot.com. If you are using an OCZ Vertex 2 Series 2.5" 120GB SSD MLC Internal Solid State Drive and have the kernel panic lockup at wake-up then it is the firmware that is the issue, not the data doubler. Once you update the firmware it should clear up the problem. For me I had to have the drive as the primary drive with a factory internal CD drive installed to pull off the firmware upgrade. Anyway, I hope my tutorial helped.
