And how does he knows we should load > i40e, instead of ixgbe? `depmod` may put hardware/driver lists into initramfs when `mkinitrd` is called when a new kernel is installed. Also check file: /lib/modules/`uname-r`/modules.alias The modules.alias contains PCI vendor/device IDs which can be found via `lspci -n`. Also you can `modinfo i40e` and `modinfo ixgbe` to see a list of PCI vendor/device IDs which each driver supports. Most of the time “it just works” be can be confusing tracking down exactly why one driver loads instead of another. > _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
