Title:
  [Lenovo ThinkPad x220] Ubuntu crashes

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  I guess this bug may relate to Ubuntu drivers. I'm using Lenovo x220
  with Ubuntu 12.04. Everytime when I was trying to plug out my
  headphone from the USB port and moving my Trackpoint at the same time,
  Ubuntu would crash. A black screen with various system output show up
  and the light of the CAPS LOCK flashed. I had to power off the
  computer and restart.

  I guess some driver is wrong with the trackpoint because most of the
  crashes were related to trackpoint and trackpoint in Lenovo machine is
  quite unique.

  Please take a look and appreciate any advice.

  Thanks.
