Bug description:
  To reproduce:

  1. Have a wired xbox controller.
  2. Modify the SDL2 testrumble.c so it runs forever. (attached)
  3. Build and run it.
  4. Kill it with sigkill from another terminal.

  Expected result: The program should stop running.

  Actual result: Entire computer freezes. Soundcard continuously plays
  the last second of audio. No response from any input devices or the
  network.

  The bug can also be reproduced by playing the game Borderlands 2 while
  having a wired xbox controller connected. The system will randomly
  freeze in the exact same way.

  The bug has existed since at least 14.04.

  The last thing the kernel prints is this:
