Title:
  Freeze of mouse and keyboard after suspend due to i2c-designware

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  when I blacklist :
  blacklist i2c_designware_platform
  blacklist i2c_designware_core
  In /ect/modprob.d/blacklist.conf
  my system resumes perfectly.

  If I do not blacklist these modules I have erverytime my laptop
  resumes form suspend, but I have a freeze of my mouse and my keyboard.
  Capslock does not work. Mouse, touchpad and touch screen do not work.

  I have tried different kernel from 3.13, 3.14, 3.15, 3.16 and 3.17.
  The problem is systematicaly reproducible.

  These two modules are for the use of my touchpad and my touchscreen.

  These crashes affect  Unity and KDE
