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:
