Public bug reported: 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.
