Re: [Discuss-gnuradio] benchmark_* not working correctly

[Tim Meehan]

Were either of you able to resolve this?  Any hints on where I might try to find the problem?  I spent some time digging around pkt.py.

I get similar results running svn 6504 under Debian testing (Lenny).  This was a fresh install on a clean machine.  I do not see the same problems on a similar debian machine running an older version of the trunk. 

ok = False  pktno =   14  n_rcvd =    1  n_right =    0
ok = False  pktno =  189  n_rcvd =    2  n_right =    0
ok = False  pktno =   98  n_rcvd =    3  n_right =    0
ok = False  pktno =  134  n_rcvd =    4  n_right =    0
ok = False  pktno =  156  n_rcvd =    5  n_right =    0
ok = False  pktno =  207  n_rcvd =    6  n_right =    0
ok = False  pktno =  222  n_rcvd =    7  n_right =    0
ok = False  pktno =  238  n_rcvd =    8  n_right =    0
ok = False  pktno =  218  n_rcvd =    9  n_right =    0
ok = False  pktno =  358  n_rcvd =   10  n_right =    0

Just to clarify, the Fedora desktop is receiving every packet in the
correct order with passed CRC, while the other computers seem to only
pick up maybe 1/20th of the sent packets and never pass the CRC check.
These computers all ran these tests correctly early last month iirc.
I'll continue to look into it.

Thanks,
