Bug check description: This bug check indicates that the driver is in an inconsistent or invalid power state. This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. The crash took place in the Windows kernel. Possibly this problem is caused by another driver that cannot be identified at this time.

Edit/Update In attempting to fix this issue, my laptop went into and endless boot cycle and I had to do perform a repair installation. This essentially 'reset' my laptop, without a full reformat. What I discovered is that the Samsung settings software may be the culprit. As I took several days to update my machine back to it's prior state, the hibernation was working properly. However, when I installed the Samsung settings app (I will update with the actual name), hibernation was removed as an option in power settings. With these laptops, you need the Samsung software to use some of the specific keyboard features. Now, my machine will sometimes go to sleep, but occasionally something interferes with auto sleep settings.

ok, the dumps shows that the tunnel.sys causes it:

This is a known issue in Windows 8.1, that Microsoft already tried to fix. But I can see that you have the fix already installed. Your tunnel.sys has the version 6.3.9600.18048. You should contact the Microsoft support and tell them that the update doesn't fix it.
