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.
