Yes, it's the lb_method=pf_ring that enables it.

What do you want to change it to? I think it's doing 4-tuple or 5-tuple by default right now.
One problem you will encounter is a issue with pf_ring cluster_id choice. You will be running two pf_ring clusters on the same host (i'm assuming that nsm1 is the same physical host) and pf_ring doesn't like that. It does something weird like trying to stick packets from both NICs into the same queue. We have it fixed for our next release (that did get merged into master, right Daniel?) but it's a problem right now.
You are sending us enough information to determine why you're seeing crashes though. Could you send the output from broctl diag nsm1-eth5-1 (assuming that's a host that is currently crashed)?
