After rebooting the machine and starting the game "Medieval 2:total war", and not giving any input from the keyboard after the game starts, the game will crash the system.
Steps to Reproduce:
While I wasn't able to reproduce this on my machine using my AMD RX480 card, my co-workers machine using an AMD R9 270 seemed pretty consistent.
As stated above to reproduce the issue: after a reboot of the machine, if the game is started through steam and left alone with no input from the keyboard the machine will freeze.
I've been having trouble getting any log messages or output as the machine will freeze completely needing a hard reboot. If I can get any I will post it here.
