(Get the code!)
At random lenghts of runtime, after booting Precise on my Alienware M15x, the keyboard goes completely wonky.
The symptoms for this are varied. Usually, they involve what seems like a hung keypress, so, for example, if I press Alt-Tab to switch windows, and release the Tab, as long as I have Alt pressed the switcher rapidly scrolls through open windows unstopped.
Or, if I press and hold the space bar, the system continuously spits out spaces. OR, if I scroll a web page using the up or down arrows (or try navigating large files using less in a terminal window) the arrow key appears to become stuck until I press a different arrow key.
Another symptom is that keys stop responding on the first press. I may have to type each key twice to get the letter to appear in whatever I am typing in.
Logwise, I consistently see atkbd error messages flooding syslog like this:

At this point, the only thing I can do is reboot the system to recover. Needless to say, this makes Precise on my system a very frustrating experience.
Unfortunately, I can use apport to add logs because of this bug: #984256 which makes apport all but unusable.
