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. ** Tags added: latest-bios-2.21 ** Changed in: linux (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1342570 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.
