I have a high pitched whine coming from my motherboard when the EHCI
USB 2.0 controller is enabled in the BIOS.  The whine only starts once
FreeBSD 7.0-RELEASE is halfway through booting.

The whine also goes away when I plugin a USB drive in with EHCI
controller enabled (usb keyboard and mouse being already plugged in).

Is this a hardware problem, or could it possibly be software related???
