Bug 200420 might be related without the crash in the 10.x branch. Same adapters (I210), motherboard Supermicro X11SBA-F. Can you retry with 12-CURRENT? (In reply to Kevin Bowling from comment #3) Sorry for delay, never saw this comment. I've just re-tested the same hardware using Current at r308389 with no change to results/symptoms. I'll retry with something more recent. (In reply to rpp from comment #4) Tested with today's head at r319962, and can't reproduce problem, so appears its fixed. Can this be MFC'd to 11? If not, any idea where/what the change would be so we can create a local patch? Changing Version to 11.2-STABLE assuming it's still an issue there. This NIC is well supported in FreeBSD 12+. Closing as OBE due to comment #5 and FreeBSD 11 EOL. |
Created attachment 171625 [details] crashino core.txt.1 Kernel panics within a few seconds with heavy network load. Using "iperf -c another_host" is sufficient to induce the problem. Setting hw.igb.enable_msix=0 in loader.conf "solves" the problem. The problem occurs on at least 2 similar machines with same motherboards. Hradware is Asus P9D C224 with integrated <Intel(R) PRO/1000 Network Connection, Version - 2.5.3-k. crashino core.txt.1 attached. --Richard
