Sorry, I thought I had reported months ago that this was no longer an
issue for me, but it seems I had not... The last LTS fixed this
completely for me.

Title:
  Strange noise at shutdown, reboot or sleep

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: linux-image

  The bug appeared when I tried to upgrade my ubuntu from maverick to
  natty. My kernel under maverick is 2.6.35, the kernel under natty was
  2.6.38.

  Description of the bug : the computer works perfectly fine, but when I
  shut it down, there is a loud "crack" (not a beep) at the very end of
  the process. It is probably not a speakers cracking, because I have
  tried it with external speakers, and the sound still came from the
  computer. It does the same for hibernation or sleep, except that the
  noise is done twice when put to sleep. The noise appears too with the
  natty live-cd (when I shut down, it appears just after removing the
  cd).

  I think it is a kernel bug, because when I boot on a older kernel
  (grub still proposes old versions), there is no problem. I tried
  installing 2.6.39 to see if it helped, but the noise is still there.

  I am using a HP Pavilion DV6000 laptop (dual boot ubuntu/vista).
