Hello, I am able to reproduce a kernel panic using the i40e-1.5.18-zc drivers. When I have a PF_RING application running using an interface (in this case eth2) If I run tcpdump on this interface at the same time, then exit tcpdump it will consistently cause a kernel panic. The logs indicate this happens when tcpdump tries to leave promiscuous mode. >From what I can see, the device resets when promiscuous mode is toggled which causes PF_RING to raise an error since the device is in use.
This is the kernel log of when it had happened: http://hastebin.com/hibonigira.md After this happens, the system hard-locks and requires physically rebooted. Thanks
