I would prefer to have power-saving on as it is a portable device but this does stop the remaining messages about the queue.

Finally I get extensive logging of 

[ 1137.214502] Bluetooth: hci0: Out-of-order packet arrived (0 != 1)
[ 1142.185255] Bluetooth: hci0: Out-of-order packet arrived (1 != 2)

[ 1143.287232] Bluetooth: hci0: Out-of-order packet arrived (6 != 7)

When I am running a bluetooth scan and/or connecting to a device, this seems harmless but does spam dmesg quite a bit.

Thanks,
