Subject: After kernel update: connect/disconnect forever while attempting to auto-reconnect

Hi,

after upgrading to kernel 5.1.1 (and also 5.1.2) my bluetooth speakers
are unable to auto-reconnect. I can connect them without problems, but
once I turn them off and on again an unending sequence of connections
and disconnections begins:

---- manual connection ok ---------
[bluetooth]# connect E0:D1:E6:07:62:E1
Attempting to connect to E0:D1:E6:07:62:E1
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
Connection successful
[CHG] Device E0:D1:E6:07:62:E1 ServicesResolved: yes
---- turned off speakers and on again ----
[CHG] Device E0:D1:E6:07:62:E1 ServicesResolved: no
[CHG] Device E0:D1:E6:07:62:E1 Connected: no
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
[CHG] Device E0:D1:E6:07:62:E1 Connected: no
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
[CHG] Device E0:D1:E6:07:62:E1 Connected: no
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
[CHG] Device E0:D1:E6:07:62:E1 Connected: no
[CHG] Device E0:D1:E6:07:62:E1 Connected: yes
[CHG] Device E0:D1:E6:07:62:E1 Connected: no

I've tested this with a number of kernels:

linux-lts 4.19.43: doesn't work
linux 5.0.13: works
linux 5.1: works
linux 5.1.1: doesn't work
linux 5.1.2: doesn't work

All the above tests were done against bluez 5.50. I've also tested
bluez git master against linux 5.1.2 to no avail.

During failed attempts to auto-reconnect, the debug log shows:
