I seem to missed pointing which URL I used to realize trusty is not following immediately my know last good release:
https://launchpad.net/ubuntu/trusty/+source/linux

Also one more thing that may help to locate the bug. I noticed that, in whichever release this resume issue exists, I also cannot change the brightness of the laptop.
When I change the laptop the ruler changes, but it makes no affect to the existing brightness. Maybe related...

Title:
  Dell 5737 freezes on ubuntu14 everytime during resume from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  My dell 5737 laptop was running all fine on 12.04. As soon as I
  upgraded to 14.04 I am consistenly running into system freeze
  everytime system attempts to resume from suspend. This happens when I
  simply close the lit of my laptop or due to screen inactivity
  suspend... When that happens only thing that works is hard reset. This
  is 100% reproducible.

  Interestingly, I noticed that on 3.11.10 kernel if I suspend manually
  from menu, the laptop resumes just fine.

  I tried pretty much all kernels upward including 12.04 ppa, even
  upgrading to 14.10 does not help. I am currently running
  3.16.0-24-generic kernel. I even upgraded my BIOS to A10 (even though
  it was clearly stated optional on Dell site).

  When I boot using 3.11.10 kernel all is well except my virtualbox no
  longer functions then.
