Ok, I downloaded the 12.04.04 Mythbuntu, installed it.

I'm still rebuilding the box, but absolutely so far no problems at all, but 
I've managed a ~3 hour uptime in between (on purpose) reboots, and couldn't 
get anywhere near this in 14.04.

I don't know quite what the problem is in 14.04.1, since I had lockups also 
with the nouveau driver as well as various nVidia binary blob versions.

If I had to guess, I'd say it's something in the grub/boot graphical 
"logo-screen" code along with nVidia hardware.
