peer manager initialization stucked

[User1321]

I had a BLE central application and need to migrate now to peer_manager to have the LESC security. 

I am using as a reference the Experimental: LE Secure Connections Multirole Example  example.

Application compiles ok, but it gets stucked in peer manager initialization, in pm_init() fcn, specifically in nrf_crypto_rng_backend_init() inside inside sm_init() .

This event just happens when LESC is enabled. If PM_LESC_ENABLED is disabled, then application at least starts.

When i try the original examples it works properly. Any idea what would be the reason for this? 

I am using the nrf52840, thus s140.

Update:

I realized that it gets stucked inside pm_init() if i call the app_timer_create() before peer_manager_init(). 
Once that i set all timers after the peer_manager_init() application runs ok.
