https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=239240 Bug ID: 239240 Summary: igb: TX(2) desc avail = 1024, pidx = 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 least a few minutes after) I started receiving "igb6: TX(2) desc avail = 1024, pidx = 0". The interface no longer works and will continue to print the message until 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 anything else that may help. pciconf -lv igb6@pci0:0:20:3: class=0x020000 card=0x1f4115d9 chip=0x1f418086 rev=0x03 hdr=0x00 vendor = 'Intel Corporation' device = 'Ethernet
