Decoding that message gets me:

>>>>>> QMUX:

>>>>>>   service = "ctl"
>>>>>>   client  = 0

Which decodes to:

>>>>>> QMUX:
>>>>>>   length  = 23
>>>>>>   flags   = 0x80
>>>>>>   service = "ctl"
>>>>>>   client  = 0
>>>>>> QMI:

Etc, with similar release CID messages for different subsystems.

These messages are highly unexpected at this stage. I cannot explain
why they appear. Are you absolutely sure that there is nothing else
talking to the modem here?

Or maybe these messages are "leftovers" from a previously failing
session? If so, then I believe it would be useful to have the debug
outout from the _first_ failing ModemManager session after a clean
modem boot.
