Hi, I think your log is cut short. At least in what you posted I don't see the "card skipped" issue anymore. Also I don't see the segfault at the end anymore. Actually there is no error left in this second log.
I never used basicfwd so far - maybe it is something special to it that breaks your case. If it follows the normal EAL commandline I'd recommend to also add something for memory like --socket-mem 2048. Well without it should just try to grab everything, but I prefer to specify things. Could you try to run the testpmd or l2fwd programs instead - IMHO these are more commonly used (=usually work better).
