https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D239240 Bug ID: 239240 Summary: igb: TX(2) desc avail =3D 1024, pidx =3D 0 Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: standards Assignee: standards@FreeBSD.org Reporter: ultima@freebsd.org Currently, I have a router running FreeBSD 12.0-RELEASE on atom c2758. My switch seems to have become unresponsive which required a hard reset. Sometime around when the switch became unresponsive, (I think it was at lea= st a few minutes after) I started receiving "igb6: TX(2) desc avail =3D 1024, pi= dx =3D 0". The interface no longer works and will continue to print the message un= til the interface is down. Bringing it back up will start the message again. Most of the settings are below. There is a lot that were removed as I don't think they have any relevance to this issue. Let me know if there is anythi= ng else that may help. pciconf -lv igb6@pci0:0:20:3: class=3D0x020000 card=3D0x1f4115d9 chip=3D0x1f41808= 6 rev=3D0x03 hdr=3D0x00 vendor =3D 'Intel Corporation' device
