Is this problem coupled with a high utilization of CPU by Xorg?

Bug description:
  Hardware: Lenovo X200 laptop
  OS: Ubuntu 12.04

  Bug occured after upgrading from 11.10 to 12.04

  Bug:

  Originally reported a few weeks ago here:
  http://ubuntuforums.org/showthread.php?p=11869633

  Short recap:

  At a random time after login (never less than half an hour so far), 
approximately once every other day (after upgrading 6 weeks ago), the keyboard 
stops responding as usual. It seems that the initial keypress is disregarded, 
but key registers after the repeat-interval and then repeats as usual - i.e. I 
press a key and wait and the key registers and repeats just as it would before 
the bug appears except the first keypress is not registered. I cannot trigger 
this bug "at will", and I see no traces of errors in any error log.
