I'm experiencing the same problem, and I can confirm that Alexander's workaround fixes it. Here is some more information: * I see the exact same problem on two different systems, both with S5520HC motherboards. * Both systems have two igb ports, and igb1 works on both. Only igb0 is br= oken. * Disabling tso, lro, rxcsum, and txcsum has no effect. * tcpdump reveals that igb0 transmits successfully, but fails to receive * Curiously, "netstat -I igb0" shows nonzero values for Ipkts, even though "tcpdump -i igb0" shows no inbound packets at all. * I can't really tell if IPv4 or IPv6 are working, because even ARP doesn't work. * SVN revisions 291495 and 292570 are both bad. I don't know any recent good revision. -Alan On Thu, Nov 19, 2015 at 11:21 PM, Alexander Leidinger <Alexander@leidinger.net> wrote: > Dual stack. > Ping was on ipv4, no answer.
