Petr Stehlik, 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. For example:
kernel-fixed-upstream-3.16-rc5

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 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!
