Title:
  Sometimes system works too slow

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Bug starts to show up after last kernel update (3.8.0.21.37).
  Sometimes system works very slow. 'top' command shows that many
  processes produces 40-50% CPU loading. Processes every time are
  different. Once udevd daemon produced 70% CPU loading and even 'ps'
  command freezed when it's output was on udevd. java (tomcat, I think)
  and xorg produces over 100% thery often. CPU cooler during this works
  on maximum frequency and doesn't stop. CPU temperature increases to
  60-65C.

  After reboot everything works fine. Now summary CPU loading less then
  10%, temperature - 40-45C. In spite of I have several hard programs
  (eclipse, chrome, thunderbird and other) launched.
