Title:
  [Lenovo ThinkPad Twist] Bluetooth subsystem dies after suspend

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I am using Saucy in XMir mode with the standard Unity desktop on the
  Lenovo Thinkpad Twist.

  When I suspend the system not only the suspend itself is broken (bug
  1213233) but also after waking up I cannot use my Bluetooth devices
  any more (mouse, keyboard). I have to reboot to get Bluetooth back
  working.

  Do not ask me to update the BIOS from 1.52 to 1.57, this leads to bug
  1210748.
