apport-collect -p linux 1342570 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete ** Tags added: regression-release -- 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. Thanks!
