As I was unable to usefully bisect the ubuntu kernel, I tried again with
the mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/

This gave a much clearer result:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14.37-utopic/ -- works
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc1-trusty/ -- crashes on bootup

I was also able to reproduce a crash on bootup with: 
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc4-utopic/
-and-
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-utopic/


Thanks,
Geoff

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.
