You didn’t provide enough information to debug your problem. You’re also using non-standard terminology which makes it even more difficult to debug.
I only looked at two of your links, but I think you’re talking about what people call “transmit hangs”. A transmit hang and reset occurs when the transmit queue can’t be emptied. This can happen for many reasons including unplugging an Ethernet cable at the wrong time. A transmit hang is a symptom, not the cause of the error. If you’re somehow filling the transmit queue when there’s no link you’re going to see these. Without more information that’s about all I can tell you.

It goes into a reset loop. I will refrain from sending if the netif_carrrier_ok(dev) is false as a workaround. Maybe its illegal to try and send if the device is down. But it would be nice to know if this is expected behavior.

Although, Im not sure what the distro means here. I believe its only kernel version and driver version that are significant? In any case, my system is based on some embedded small distro. Maybe it was busybox. Since then we have swapped kernels. It seems ( after a quick google search of "igb reset adapter") like a common problem in various releases. Some examples: http://www.spinics.net/lists/netdev/msg231442.html http://serverfault.com/questions/559663/issue-with-intel-i350-nic https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1493753 https://sourceforge.net/p/e1000/bugs/395/ http://www.linuxhow.tk/igb-eth0-reset-adapter/ If fixed in later versions of the driver, I figured that someone here knew what was patched. I will test unpacking/compiling version 5.1.2 in my kernel tree.

I have no idea about what your distro is from what you sent, and you'll need to send a whole lot more info. Do you have a factory representative you can go through to get this filed with Intel Premier Support? That would probably be the best way to get support. If not, you can file a bug on sourceforge and attach the whole dmesg and lspci -vvv as a first step.

I am using: root@C077-0024:root# uname -a Linux C077-0024 3.0.8 #1 SMP Mon Apr 4 09:17:08 EDT 2016 x86_64 GNU/Linux root@C077-0024:root# ethtool --driver eth1 driver: igb version: 3.0.6-k2 firmware-version: 0.147-0 The error is reproduced when setting remote end to down and transmitting at the same time. Setup is back-to-back. [ 8603.660150<tel:%5B%208603.660150>] igb: eth1 NIC Link is Down [ 8605.824275] igb 0000:00:0a.0: eth1: Reset adapter [ 8607.820167] igb 0000:00:0a.0: eth1: Reset adapter [ 8609.820164] igb 0000:00:0a.0: eth1: Reset adapter [ 8611.820192] igb 0000:00:0a.0: eth1: Reset adapter It goes into a reset loop. When remote end comes back up, it continues to loop in reset. When limiting the TX the link comes back up. Is there a known way of getting around this? I would prefer not to backport the driver. -- Avis de confidentialité Les informations contenues dans le présent message et dans toute pièce qui lui est jointe sont confidentielles et peuvent être protégées par le secret professionnel.
