Public bug reported:
Binary package hint: linux-image-2.6.22-7-generic
On my MacBook (first generation Core Duo) running Gutsy pre-release, I
can hear a whining noise that first occurs when the uhci-hcd module is
loaded on boot and persists until shutdown. This occurs on both the
Gutsy and the Feisty kernels. However, I do NOT see this problem on
Debian Etch (using a 2.6.18 kernel - I *do* see it on Etch with a 2.6.21
kernel), which leads me to believe that it was something introduced
between 2.6.18 and 2.6.21.
Furthermore, the noise stops if I unload the uhci-hcd module - though,
for obvious reasons, that makes the MacBook useless. Also, if I use the
USB bus (i.e. copy music to my iPod), the noise stops for the period
during which the USB bus is in use, but returns afterwards.
I have reported this upstream to lkml and the uhci maintainer, but
wanted to make sure that this could get fixed in time for Gutsy.
