[Hans de Goede <jwrdegoede@xxxxxxxxxxxxxxxxx>]

Hi all,

I just hit the same problem, and I've managed to fix it for my case
(Dell E6430 laptop with integrated bluetooth).

I've had exactly the same experience as Till, in that 3.11 caused bt to
no longer work after a suspend/resume for me. I'm surprised to hear that
the problem has magically gone away for Till, as there is a very real
reason causing it in the form of a "fix" in 3.11 .

I've written a patch for this (reverting the fix) and send it upstream.
I'll also attach it here.

Regards,

Hans

Title:
  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.
