Not a permanent solution. On two separate systems with Intel S5520HC motherboards, FreeBSD CURRENT ca= nnot receive any packets on igb0. igb1 works fine, and igb0 works when booted i= nto FreeBSD 9/stable. * 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. * Alexander Leidinger reported a similar problem, but didn't specify whether all igb ports were broken or only one (or even whether he had multiple port= s).=20 He reported that 11-CURRENT worked at svn r287323, but failed at r290633. * Alexander also provided the attached patch, which fixes the issue. --=20 You are receiving this mail because: You are on the CC list for the bug.=
