[Bug 1385937] Re: [Acer Travelmate B115-M] Synaptic touchpad not correctly detected in kernel 3.16 after upgrade to Ubuntu 14.10

 

This is my bisecting result but actually some v3.14 commits I had to
skip since I could not start them:

There are only 'skip'ped commits left to test.
The first bad commit could be any of:
