Changing the log level to "error", using n_prb = 15, first gave me the
following result:

LLError receiving from UHD: 30
USRP reported the following error: None
LLError receiving from UHD: 30
USRP reported the following error: None


Then running uhd_usrp_probe once between tries fixes it and now it works
with the configuration above.
