Bug description:
  Since updating to raring from quantal, two of my machines (a
  MacBookPro 5,1 and a MacBookAir 4,1) have exhibited this behavior. It
  seems to be more of a problem the faster I type, but that just
  increases the frequency of keypresses. Ocassionally while typing a key
  that I have pressed seems to stay "stuck down" and further input while
  that is going on is missed. The character repeats maybe 10 times, and
  then everything is back to normal.

  I don't have a way to reproduce this reliably, sometimes there are
  many hours between seeing it.

  One data point I do have is that it even happens when using synergy to
  control the raring box from a quantal machine, which is why I am
  reporting this against xorg and not the kernel where it might be
  construed as a USB or keyboard issue.
