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).
