This system has a pair of bonded gigE links used for booting and management, and a pair of bonded 10G links used for data traffic. What we're seeing is that when ip_auto_config() calls ic_open_devs() to open up all the network ports, the data ports immediately start getting *hammered* with traffic, we get "nf_conntrack: table full, dropping packet", errors, and we sometimes lose the DHCP responses because of this. We need to be able to boot off of both the gigE ports for redundancy, so it seems like it might be a reasonable idea to extend the "ip=" boot arg to allow specifying a list of devices rather than choosing between a single device or all of them. Thoughts? Anyone ever done this? Chris -- Chris Friesen Software Designer 3500 Carling Avenue Ottawa, Ontario K2H 8E9 www.genband.com
