0.92 Hassbian doesn't start

Hello,
just upgraded to 0.92 and my hassbian is veeeery slow to start:
it hangs with:

2019-04-25 01:26:16 INFO (MainThread) [homeassistant.setup] Setup of domain device_tracker took 11.3 seconds

And it stays there!
It’ about 25 minutes right now.

How can I debug it ?

Thanks!
