Public bug reported:
When my usb headset is plugged in using the 2.6.32-24 kernel there is a
cpu lockup. This also causes the gui to lockup and the keyboard is
unresponsive. A hard reset is required to use the computer again.
This is the specific information from when the usb device is plugged in
from the kern.log
