This appears to still be an issue on the latest 5.4.0-99-generic kernel. I'm using a 2 port 10GSFP+ card. The PCI driver isn't bound according to lspci, and the interfaces don't show up in dmesg or "ip link". # lspci -nnk 31:00.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection X722 [8086:37cc] (rev 09) DeviceName: 10Gb Ethernet1 Subsystem: Lenovo Ethernet Connection X722 [17aa:4021] # modinfo i40e ... version: 2.8.20-k description: Intel(R) Ethernet Connection XL710 Network Driver ... vermagic: 5.4.0-99-generic SMP mod_unload modversions Strangely the ports don't even come up with the latest 5.13.0-28 kernel. # modinfo i40e (no version) vermagic: 5.13.0-28-generic SMP mod_unload modversions The card works perfectly in another distribution with the i40e driver, but that's running a 4.18 kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887703 Title: [Regression] 5.4 is not identifying all ports on Intel x710-TM4 10GbE controller To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1887703/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
