Hi, I buy "Intel X710-DA2" and insert in one SFP+ 10Gb modul. After inserting to our linux router all working, but after 30 minutes kernel crash. Before this all communication working and bit rate through NIC is about 200Mb. Can you help me ? I don't know if problem is linux (software) or hardware.
Motherboard is Supermicro X10SLL-F I use PCIe 16x slot. in /var/lof/messages I found Nov 3 06:47:52 rco kernel: [ 1850.532801] i40e 0000:01:00.1: Malicious Driver Detection event 0x00 on TX queue 16
