Hi, For some reason I spend some hours, two days in a row, trying to debug why a newer kernel didn't work on our machines. It worked just fine with the older kernel...
And there was no network interfaces to see or try to figure out what was going on with. Playing with the infiniband tools all i could see was things like: ... state: 1: DOWN phys state: 3: Disabled cat: /sys/class/infiniband/mlx5_0/ports/1/rate: Invalid argument rate: unknown link_layer: Ethernet ... It turns out that the kernel was compiled with mlx5_en disabled, since it's the default Unless there is a really good reason not to, lets change the default value to 'y' =) I'm hoping that this will lead to others not experiencing the same surreal journey of trying to debug this ;) ---- The mellanox driver supports both ethernet and infiniband, but it is located in the ethernet drivers - the ethernet support should default to 'yes'.
