You are right to clarify.

My concern is that this problem appears "randomly" for each kernel
version, even on minor updates on 14.04 kernel (has I said at the
beginning), so I wanted to give a global vision of the problem.

The link to the SRU procedure is very interesting, but :
 - I do not have much time to do this.
 - I do not understand enough all the implications this could have.

Anyway, thanks for your time, and maybe I will follow the SRU procedure if I have time and courage.
Yvan

Title:
  [MacBook7,1] suspend/resume failure

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  Hi,

  Using Xubuntu 14.04, the MacBook7,1 can't resume after a suspend to RAM since laste kernel update (linux-image-3.13.0-39-generic). The screen does light a fraction of second, but remains off after that. It happened sometimes with kernel linux-image-3.13.0-40-generic, but with last kernel it happens on each resume.
  I am using the nouveau free driver.

  Thanks very much for your time and work,
  Yvan
