Title:
  Bluetooth RFCOMM: Transport endpoint not connected (kernel regression)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 12.04's "Hardware Enablement Stack (HWE)" check forced me to upgrade to trusty's kernel:
  * Install a newer HWE version by running:
  sudo apt-get install linux-generic-lts-trusty linux-image-generic-lts-trusty

  Since then bluetooth communication fails with "Transport endpoint not
  connected". It does work OK if I reboot back to soon-to-be unsupported
  kernel 3.5.0.x

  This is a known kernel 3.13 regression, please see
  https://bugzilla.redhat.com/show_bug.cgi?id=1060457

  If it is indeed fixed in kernel 3.14 please backport the fix to
  trusty's kernel, or perhaps get 3.14 kernel into trusty. The current
  3.13 is not a good upgrade.

  Thanks!
