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.
