Benjamin Staffin, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested exactly shown as:
kernel-fixed-upstream-3.18-rc3

This can be done by clicking on the yellow circle with a black pencil
icon next to the word Tags located at the bottom of the bug description.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  bluetooth hci interface "down" on every reboot

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Each time I boot up, bluetooth doesn't work until I run "hciconfig
  hci0 up". Then it seems fine until the next reboot. This may be
  related to bug #1244764.

  Before I run hciconfig hci0 up:
  - rfkill indicates that the bluetooth device is *not* blocked.
      $ rfkill list
      0: phy0: Wireless LAN
              Soft blocked: no
              Hard blocked: no
      1: hci0: Bluetooth
              Soft blocked: no
              Hard blocked: no

  - The gnome control center bluetooth module thinks that bluetooth is enabled, but scanning does not work. These messages appear in syslog when I click + to add a device:
      bluetoothd[605]: Discovery session 0x7f5fa71df5e0 with :1.93 activated
      bluetoothd[605]: hci0: Start Discovery (0x0023) failed: Not Powered (0x0f)

  Then I run:
      $ sudo hciconfig hci0 up

  At that point in syslog:
      bluetoothd[605]: Adapter /org/bluez/605/hci0 has been enabled

  Then when I try to scan for bluetooth devices it works, with this in syslog:
      bluetoothd[605]: Discovery session 0x7f5fa71dada0 with :1.94 activated

  I can just add an upstart service that runs hciconfig hci0 up at every
  boot, but that shouldn't be necessary if everything works correctly.
