In CC2538 platform the random number initialization should not be started after the radio. Then the mote reboots.

please check the warnings under cpu/cc2538/dev/random.c->random_init().

Random number initialization is called in dtls_new_context function with dtls_prng_init(now) call.

My current suggestion is omitting the random number initialization for cc2538 platforms.
