Joseph, I've already mentioned that I am unable to test 3.15rc since it
boots with a completely black screen start to finish. I don't know what
is the cause and how to circumvent it.

Title:
  [Dell Inspiron 1525] Trusty freezes on resume from suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The issue hit the system right after uprading from Saucy to Trusty.
  Ubuntu Trusty freezes on resume from a suspend on a DELL Inspiron 1525
  machine. All I see is just LEDs for disk (just blinks for a moment)
  and wifi (stays lit), fan noise and a black screen. No mouse cursor,
  no nothing. The magic SysRq (+REISUB) does nothing; a hard manual
  reboot by pressing the power button is necessary.

  The problem is gone if booting with a 3.11-20 kernel left from Saucy.
  The issue is present, however, at least with 3.13.{8,11} and
  3.14.{1,2} mainline kernel builds. I haven't tried 3.15rc, though,
  since it boots with a totally black screen and I have no idea how to
  bypass it; and my Broadcom wifi driver fails to build with 3.15rc too.

  I believe it is the same bug as Bug #1310823 and am just reporting
  this in order to upload my system's data.
