Title:
  bluetooth hci interface "down" on every reboot

Status in linux package in Ubuntu:
  Expired

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.
