Hi Christopher,
I've tried the available pre-built packages but there are graps between the binaries and upstream.  The early 3.16.0 kernels work for me but with no graphics acceleration, which I think is why they don't crash.  It looks like the later builds switch acceleration back on and thats when the problems occur.

So I think the *real* problem must lie somewhere between 3.13.0-44 and
the version of the kernel before 3.16.0-23 that still had graphics
enabled.

Here are the results I've come up with so far:
linux-image-3.13.0-44 (trusty) - OK
linux-image-3.13.0-44 (trusty) - OK
linux-image-3.16.0-23 - Doesn't crash but seems to be using framebuffer video + no sound
linux-image-3.16.0-28 - Doesn't crash but seems to be using framebuffer video + no sound
linux-image-3.16.0-33 - accelerated graphics working but crashes
linux-image-4.0.0-rc6 - seems mostly working but crashes on shutdown (observed twice)

Title:
  frequent lockups asus g705js/GeForce GTX 870M

Status in The Linux Kernel:
  New
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I get hard lockups with Linux kernel 3.16 every 5 - 15 minutes.
  Attempted upgrading to (x)ubuntu 14.10 to see if this improved
  stability and laptop crashed so badly during the upgrade that it broke
  grub and had to be recovered with ubuntu boot-repair. This allowed the
  system to boot and I was able to complete configuration with dkpg
  --configure -a --pending

  System still crashes every few minutes when running (x)ubuntu 14.10
  and about 50% of the time crashes before even reaching the login
  screen.  If I'm lucky attempting to swich VCs will resolve things but
  the system always crashes eventually and has to be powered off by
  holding the power button for 10 seconds or via the magic sysreq key.
  No other key cominations work.

  WORKAROUND: Boot into kernel 3.13.0-44-generic.
