Title:
  BUG: unable to handle kernel NULL pointer dereference at IP:
  [<ffffffff81044a99>] __ticket_spin_lock+0x9/0x30

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  System details:
  Dell Inspiron E1505. 2GB RAM, 200 GB SSD.
  I have a Logitech Dinovo Edge keyboard which I am able to pair, connect and then use.
  Every once in a while I get this kernel oops and it drops to text. Its possible to get back to X with Ctrl+Alt+f1 and the C-A-f7.
  However, the bt keyboard then no longer works.
  Rebooting the machine results in a hang. The only recourse so far seems to be to hard reboot.
