I was having the same issue after I had to hard reset on system lockup
on 3.15.1 mainline.

cat /var/log/pm-suspend.log revealed the following.

Running hook /usr/lib/pm-utils/sleep.d/60_wpa_supplicant suspend suspend:
Failed to connect to non-global ctrl_ifname: (null) error: No such file or directory

I reinstalled pmutils, hdparam and anacron and suspend/resume work
again.

Title:
  [Lenovo ThinkPad T440s] suspend/resume failing

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Sometimes, the system will appear to go to sleep mode (i.e. the LEDs
  will start indicating sleep mode). However, it appears to not suspend
  completely and the system produces a lot of heat while it is in this
  state which is rather dangerous if you put it in your sleeve and leave
  it there the system will overheat quickly. The problem exists both
  with the default Ubuntu and the mainline 3.14 kernel.
