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!
