Became fine again on Saucy, now running Trusty without issue. The fact
that this comes and goes with varying kernel families tells me this is
tied into the kernel somewhere... but in any case, it's working now and
I really don't care to fight with this any more (this is actually the
second long-running bug I've had about this issue, and countless
production, devel and test kernels attempted with varying degrees of
success.

Title:
[Alienware M15x] Keyboard becomes all but unusable after Precise runs
for so long
Status in The Linux Kernel:
New
Status in “linux” package in Ubuntu:
Invalid
Bug description:
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.
