Thanks for testing, Till.

I'd next try to identify which 3.11 release candidate introduced the
regression.

Can you test the following kernels and report back? We are looking for
the earliest kernel version that exhibits this bug:

v3.11-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc1-saucy
v3.11-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc2-saucy
v3.11-rc3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc3-saucy/
v3.11-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc4-saucy/

You don't have to test every kernel, just up until the kernel that first
has this bug.


Thanks in advance!

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.
