Problem Description:

When typing on the notebook's keyboard, it happens from time to time (quite
often, though) that when you press a key and release it (ordinary typing), that
it behaves as if you wouldn't release it at all. You then have to press (and
release, possibly) any key again, in order to stop the autorepeat of the failed
keypress. It is quite annoying to type something when getting unexpected
autorepeats once every while. I first thought, that it may only be some dust and
dirt in the keyboard, but it doesn't seem behave like that in the Windows (so
far ;) and then                   I (a good example of the consequences :) also
noticed that when it happens, lots of following messages appear in the syslog:

--------------------

Currently I use kernel 2.6.17-rc5-git9, before I was using 2.6.16-git9 and it
happend there as well. I may try                                               
    some (another good example, but it is not allways just the space, that's
just a coincidence) older kernels to see where it begins.

Steps to reproduce:

Just type on the keyboard on that notebook and kernel. :) I haven't witnessed it
on any other hardware, so far.
