[Bug 1245150] Re: 0a12:0001 Bluetooth Dongle (Cambridge Silicon Radio, Ltd) doesn't work after upgrading to Saucy


@Christopher, I once again started the bisecting process, for me the
size of kernnels built are abnormal, however I have installed them.

I had built and installed the 1st bisection. It turned out to be good
and bluetooth was working on it. Then, I built the 2nd bisection. I have
installed the files generated from 2nd bisection, but I can't boot to
it. So, I am stuck in this bisection process and can't proceed further.

Following is the output of `git bisect log`:

$ git bisect log
# bad: [c7788792a5e7b0d5d7f96d0766b4cb6112d47d75] Linux 3.10-rc2
# good: [896f5009ed1fbaec43f360c4ebf022639cd61d5f] Linux 3.9.11

  0a12:0001 Bluetooth Dongle (Cambridge Silicon Radio, Ltd) doesn't work
  after upgrading to Saucy

Status in “linux” package in Ubuntu:

Bug description:
  After upgrading to Saucy, the bluetooth-indicator was no longer
  present in the taskbar. If I go to System Settings >> Bluetooth; it
  shows as "Bluetooth is disabled" and toggling the On|Off Switch
  doesn't enable it: http://i.stack.imgur.com/vwfEo.png

  I have installed the Blueman Device Manager to solve this issue and
  its bluetooth indicator is shown on the taskbar, but it doesn't
  function. However, toggling the On|Off switch in System Settings >>
  Bluetooth, grays out the icon of Blueman indicator in the taskbar.

  To debug the issue, I am following the instructions mentioned at https://wiki.ubuntu.com/Kernel/KernelBisection. I have downloaded and installed the kernals from https://launchpad.net/ubuntu/saucy/+source/linux:
  - 3.9.0-7.15 works for me
  - 3.10.0-0.6 doesn't work

  For further commit bisecting, I have downloaded the git repository of
  `ubuntu-saucy` by running: git clone git://kernel.ubuntu.com/ubuntu

  To see how many commits are there in between, I run the following command:
  git log --oneline Ubuntu-3.9.0-7.15..Ubuntu-3.10.0-0.6 | wc
