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) [ 1142.319504] Bluetooth: hci0: Out-of-order packet arrived (2 != 3) [ 1142.446742] Bluetooth: hci0: Out-of-order packet arrived (3 != 4) [ 1142.574117] Bluetooth: hci0: Out-of-order packet arrived (4 != 5) [ 1143.160501] Bluetooth: hci0: Out-of-order packet arrived (5 != 6) [ 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.
