I was not aware this hack actually existed, but now that I see it I
think it explains why doing

echo 1 > /sys/module/bluetooth/parameters/disable_ertm

was necessary to make the controller connect over Bluetooth on my
machine. It looks like disabling ERTM just happens to have the same
effect as the hack that you mention. I'd like/plan to look into
finding a proper solution to replace that hack, but that'd probably be
a separate patch.
