Further update, According to the engineer at SMC, they did try "18.04.3" (not sure if that means 4.15, or 5.3, hopefully not 5.2) and all four ports did work for them, so this appears to be a regression in the i40e driver.
I've asked him to provide more info about what kernels they have tried specifically to help narrow down where it breaks. -- 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: 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
