Hi Christopher, I've tested a few more kernels by compiling the source packages linked from the kernel bisection page. There is NO clear breakage that I'm able to find, instead I see this:
linux-image-3.13.0.48.80 - OK (last fully functional kernel) (self-compiled) linux-image-3.13.0.49.81 - fallback graphics (doesn't seem to crash) ... linux-image-3.16.0-32.42 - fallback graphics (doesn't seem to crash) (self-compiled) linux-image-3.16.0-33.44 - accelerated graphics (crashes) linux-image-3.16.0-34.45 - fallback graphics (doesn't seem to crash ... linux-image-4.0.0-040000rc6.201503291935 - accelerated graphics (crashes on shutdown) I self-complied linux-image-3.15.0-1.3 and linux-image-3.15.0-4.8 and these both had fallback graphics and seemed to be stable.

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.
