Those are two separate issues. The first one is bug 1748565. So let's make this bug about the second issue. I can't see the kobject_add_internal_failed error in your kernel log, so where do you see it? ** Changed in: bluez (Ubuntu) Status: New => Incomplete ** Description changed: - Bugs probably in firmware: - - Bluetooth: hci0: last event is not cmd complete (0x0f) - - are causing: - kobject_add_internal_failed for hci0:11 with --EEXIST, don't try to register things with the same name in the same directory - - This issue is about kernel - it shouldn't rely on state of unrealiable propertary drivers. Sometimes rmmod all bluetooth modules helps, sometimes restart is just faster. + This issue is about kernel - it shouldn't rely on state of unrealiable + propertary drivers.
