Hi All,
This bug is back.

Under Ubuntu 14.04 LTS kernel 3.13.0-74-generic , Thinkpad T520 I had a
working SynPS/2 Synaptics Touchpad.  Then I updated to 3.13.0-76 and the
touchpad was not recognised (defaulted to standard PS/2).  I tested
several kernels up to 4.5-rc4 and they all failed in the same way.

So I reported the issue and rolled back to -74.  Then on 15/2/2016 I did
an apt-get update and it broke my -74 kernel but more than that it broke
previous kernels that also used to work (-73,-72,-71,-70).

Should I also blacklist I2C ?
