I wonder if it could be at all related ?

kobject: 'hci_usb' (f89d2948): kobject_cleanup
kobject: 'hci_usb' (f89d2948): does not have a release() function, it is broken and must be fixed.
kobject: 'hci_usb' (f89d2948): auto cleanup 'remove' event
kobject: 'hci_usb' (f89d2948): kobject_uevent_env
kobject: 'hci_usb' (f89d2948): fill_kobj_path: path = '/module/hci_usb'
kobject: 'hci_usb' (f89d2948): auto cleanup kobject_del
kobject: 'hci_usb': free name
