We couldn't trigger this bug using UDP NFS mounts. Neither could we trigger it with multiple simultaneous TCP connections. (Both tests could crash the unpatched kernel and the driver from HEAD last week - if_bce.c 1.16). We will apply this patch to all of our RELENG6 2950s and keep you posted. Thanks for all the hard work you've put in on this. Kind regards, Jason.
