Hello:
        I got two n310s。I set up them follow the guide in http://kb.ettus.com。I 
can run “uhd_find_devices”and“uhd_usrp_probe”correctly。Then I want to test them 
use the uhd/examples。I have seveal problems.
        (1)One n310 can not run 
"benchmark_rate"and"rx_samples_to_file"correctly. I have tyied seveal times, 
but got diffrent errors,and I dont know what is the problem.The file 
"benchmark_rate.log" is the log when i run 
"benchmark_rate","rx_samples_to_file_first_time.log"is the log of my fist time 
run "rx_samples_to_file","rx_samples_to_file_second_time.log" is the second 
time.


[WARNING] [CORES] Timer loopback test failed!
[WARNING] [CORES] Expecting clock rate: 122.88 MHz
Approximate clock rate: 0 MHz
 is the reason?    
      (2) The other n310 run "benchmark_rate"and"rx_samples_to_file"correctly, 
but can not run "txrx_loopback_to_file",but I got error:
Please run: sudo sysctl -w net.core.wmem_max=6250000
Checking TX: all_los: unlocked ...
Error: AssertionError: lo_locked.to_bool()
  in int _main(int, char**)
