I tested it with Ubuntu 17.10 that has a 4.13.0 kernel and still does not work but I will try the kernels you mention but unfortunately it will take me more time since they are not in Ubuntu 16.04 repository. i2c-3 name is "i915 gmbus dpc" coincidentally to what i2cdetect said in my previous comment: "i2c-3 i2c i915 gmbus dpc I2C adapter" I am attaching i915_opregion in the next comment.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
