Title:
  [HP 6710b] Kworker constantly taking about 100% CPU

Status in “linux” package in Ubuntu:
  Invalid

Bug description:
  I've this issue since the latest Ubuntu 11.10 version, all updates
  applied till today, and it's still there. Ubuntu 11.04 did not have
  this issue.

  If I run top there is a Kworker constantly taking much CPU, I don't
  know how to research where this comes from.
