Use this ISO
www.linuxcnc.org/iso/linuxcnc-2.7.14-wheezy.iso
Boot the PC from it and run the tests in Live mode, meaning do not install, see if it hangs.

Nice, that is still very usable.

RTAI kernels always had issues with hardware, mostly graphic where the resolution would be stuck at 640x480 with no options to change it, there are some examples i posted on this forum when i tested some old PC's.
And i do recall one PC would lock after a while or running LinuxCNC, at random, usually once every two to three days.

But the display works great.

Post dmesg output please.
Open up a system CPU monitor app.
Then move the mouse around a lot.
Does CPU usage go up for a process called xorg when you move the mouse around (generally indicates that sofware rendering is being used).
If it ain't broke, don't fix it.
Do you have a dedicated GPU card, by chance?

The missing firmware module can safely be ignored.
The above post can be safely ignored as well.
Tho if it is something you can do and can afford, I would recommend looking at the riocore/LinuxcncRIO project as that can connect via ethernet, is creates step/direction in hardware and as such only requires a servo thread. Another plus being you don't require a RTAI kernel. Just mentioning as this might be worth investigating. The developer is very generous with his time as well and the project is very active.
