Public bug reported:

I find that the keyboard is cutting out at random and cannot get it to work until I restart the computer. I am using a Dell Inspiron Studio, with a built in keyboard, Ubuntu 14.04 LTS, and find it is usually occuring during playing a particular game. I initially thought it could be Java (the game runs in JVM) might be doing something whereby it takes control of the keyboard, dies and then just keeps the hook, though that turned out to be nothing since even after the JVM was closed the keyboard did not respond.
I've attached the logs dmesg and xorg produce and the diff from after the error occurs.

Reading the log seems straight forward and I'm unsure how the small
changes to what appears to be my screen resolution, and what appears
also to be a small change to my kernel, are effecting the keyboard.

I have narrowed this issue down particularly to the game Puzzle Pirates,
and though I haven't had time to break this down and do a proper debug
of it, I have a feeling the issue is more then just the game, as its
effecting the entire system.
