I get this when the system boots and the interface is not there in an "ifconfig": mlx4_core0: <mlx4_core> mem 0xa2300000-0xa23fffff,0xa2800000-0xa2ffffff irq 17 a t device 0.0 on pci2 mlx4_core: Mellanox ConnectX core driver v3.7.1 (November 2021) mlx4_core: Initializing 0000:02:00.0 mlx4_core0: Unable to determine PCI device chain minimum BW If I kldunload the driver it immediately reloads with: pci2: <network, ethernet> at device 0.0 (no driver attached) mlx4_core0: <mlx4_core> mem 0xa2300000-0xa23fffff,0xa2800000-0xa2ffffff irq 17 at device 0.0 on pci2 mlx4_core: Mellanox ConnectX core driver v3.7.1 (November 2021) mlx4_core: Initializing 0000:02:00.0 mlx4_core0: Unable to determine PCI device chain minimum BW At present I do not have the other end connected to anything (I have a short-distance direct-wire SPF+ cable from Mellanox that I intend to plug into the switch in the same rack) but I wouldn't expect that to impact the driver being unable to come up. Do I have a card that FreeBSD does not support and have drivers for (although at first blush it appears it does find it)? The Nvidia documentation page has a link to an older driver intended for FreeBSD 10.1 (it doesn't resolve and neither do the release note or user manual links) Thanks in advance! -- Karl Denninger karl@denninger.net /The Market Ticker/ /[S/MIME encrypted email preferred]/
