https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D205759 Bug ID: 205759 Summary: igb cannot receive packets on first port only Product: Base System Version: 11.0-CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: sbruno@FreeBSD.org Reporter: asomers@FreeBSD.org CC: Alexander@Leidinger.net, erj@freebsd.org, freebsd-amd64@FreeBSD.org CC: freebsd-amd64@FreeBSD.org Created attachment 164902 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D164902&action= =3Dedit Alexander L's example fix. 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.=
