Suspend not working when closing lid on ThinkPad T420s

** Description changed:
Suspend doesn't work when closing the lid on my ThinkPad T420s. There is
no issue with 14.10 or 14.04. Kernel 4.0 do not help.

and at that point, closing the lid DID got into suspend.
So the issue is intermittent, and

Pirouette Cacahuète, could you please clarify which 4.0 kernel version

Suspend not working when closing lid on
Except if you have prebuilt packages for bisecting, I won't have time to
do this.
