Title:
  kernel BUG at
  /build/buildd/linux-2.6.32/drivers/char/tty_ldisc.c:707!; EIP is at
  tty_ldisc_reint+0x43/0x50

Status in linux package in Ubuntu:
  Invalid

Bug description:
  Steps to reproduce:

  1) rfcomm connect 0 <mac>

  In this case, we are connecting to a LEGO Mindstorms NXT brick.

  2) Turn off brick.

  3) After a few seconds, the system freezes.

  I did this again in the text terminal and took a picture of the
  output, will attach separately.

  This did not happen with the stock intrepid kernel
  (2.6.28-11-generic).
