I compiled bluez 4.89-71-gdc920af from git, which seems to contain the
patch that was as an attachment (9bae9813abf29344cc3d84af2ee59efd9e9e78fc).
It sometimes helps, but not always. Maybe there are some alternative code
paths, races, or something. Below some logs for a case when it doesn't
help. Also, it doesn't seem to work when bluetoothd is started before
plugging in the adapter or if the adapter is unplugged and replugged.
adapter in; start hcidump; start self-compiled bluetoothd
