The problem still persists!! I have a Fujitsu Celsius M740, which uses a i217 NIC. This NIC freezes up while under heavy I/O. In most cases, I can get it back online by bringing it first down and then up again with ifconfig em0 down/up. But sometimes I have to reboot. I get some strange errors on the console about "RX/TX no buffer left" - I'm sorry to be not more specific, I'm not in the lab at the moment where I have a more specific record of that problem. The i217 NIC suffers from this problem after IFLIB has been introduced and I can trigger the problem easily whily rsyncing poudriere repository packages with the NFSv4 connected package server. I haven't checked on igb NICs (we also use i350 based dual-port NICs as I do with some private servers). But last time I pushed them very hard with I/O, I was able to freeze them the same way. I do not know whether someone is working on this, I recall having filed a PR on this, but I was very unspecific, because I do not have further details and running CURRENT with no DEBUG features. As of your question: it hasn't been fixed so far. Kind regards, Oliver -- O.
