Sorry for the delay. I'm testing with 3.18-rc1 and will report back
shortly.

Given the amount of time that elapsed, I also see that 3.18-rc2 is out.
I don't want to conflate issues, but, I did try to  load rc2 as well and
can't do any testing, as I'm unable to boot the kernel. It seems that
something regarding cryptsetup / LUKS changed in rc2 and the system
never asks to unlock my root partition. If you want further testing on
that version, I'm blocked on resolving that. How do I report that as a
bug, given that its so early in boot?

Title:
  [Dell Latitude E7440] Touchpad out of sync

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The touchpad repetitively gets out of sync, causing the mouse to jump
  around and randomly click things:

  [  399.788431] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 lost sync at byte 6
  [  399.798582] psmouse serio1: DualPoint TouchPad at isa0060/serio1/input0 - driver resynced.

  WORKAROUND: Loading the psmouse driver with proto=exps largely avoids
  the problem, but has the side effect of merging the trackpad and the
  nub together as one input device (so you can't disable the trackpad
  and just use the nub).

  Setting reset after on the driver does fix the random moving and
  clicking, but causes the CPU to thrash as it constantly disconnects
  and reconnects to try to "resync."
