Kernel panic crash dump from /var/crash/

Using the nvidia-340 driver

I experience frequent crashes that manifest whenever I try to run a OpenGL
application.
This doesn't always happen but rather seemingly at random.
It does seem to happen more frequently when my CPU is under higher load.

The entire screen freezes, I can no longer interact with the system, mouse
locks up
keyboard locks up (or at least I don't see it respond since my screen is
frozen)
and then eventually my system just reboots.

I have to use the  -ignoreABI option when starting the X server due to my old
hardware.

I am attaching a crash.txt file created upon the crash. I can also provide the
vmcore if required (but its over 1.5GB in size).
