Title:
  [HP Pavilion dm1z-3000 CTO Entertainment Notebook PC] Keyboard
  randomly loses and inserts keystrokes (often!)

Status in linux package in Ubuntu:
  Expired

Bug description:
  With my hp dm1z-3000 laptop, while typing in several applications (ex.
  libreoffice and firefox) sometimes it starts missing characters and
  occasionally inserting extra characters - input will stop (while I
  continue to type) and after a few missing keystrokes operation will
  resume, oftenwith a few (to a dozen) extra characters are inserted.
  The extra characters will be the same (for the occurrence), and one of
  the characters I typed (I think it may be the first "missing"
  character). For example, say I was typing "partridge", and this
  problem occurs when I type the "t": I might get to the end of the word
  with "part" displaying, then "partrrrrr" might appear.

  I type at 80 words per minute. If I type at 20 words per minute, this
  does not occur. This is not a hardware fault: I replaced the hard
  drive before installing ubuntu, so I reinstalled the windows 7 drive
  to see if the problem was present.  All keyboard operations returned
  to normal with the Windows disk.  I again swapped out the disks, then
  reinstalled Ubuntu from scatch, reformatting the disk. The fault
  continues to occur.

  I note that when this is occurring, I find the following in syslog:
