Proxmox 9: Broadcom 57414 in Dell Server not working

[smalchow]

This relates to an upgrade as well as a fresh installation.

In Proxmox 9 our Broadcom 57414 network cards vanished, physically the are available but the driver does not recognize them

i tried installing the latest broadcom DKMS drivers/kernel modules before the upgrade as well (i also installed the necessary headers and dkms obviously), which worked again fine in PVE8 but not in 9.

The 100/200G Nics in the same system work just fine

please check/post the journal after booting when the cards are not available - new kernel/new systemd version might change the names of the NICs - the journal should tell you if there's a problem there.
physically available means that they are listed in `lspci -nnk`?

i tried installing the latest broadcom DKMS drivers/kernel modules before the upgrade as well (i also installed the necessary headers and dkms obviously), which worked again fine in PVE8 but not in 9.

In most cases I'd recommend not installing DKMS drivers for hardware which has drivers in-tree - do you have a particular need for the DKMS drivers for those NICs?

I have to do that again and see what happens currently all systems are back to 8.x - but i checked when we tested the upgrade/fresh installation, in the journal i did not see any visible error the cards were also not availabe with other names (we know that issue already), and yes, "physically" means "lspci".

The cards just dont show up as usable cards while these

Ethernet controller: Broadcom Inc. and subsidiaries BCM57508 NetXtreme-E 10Gb/25Gb/40Gb/50Gb/100Gb/200Gb Ethernet (rev 11)

are no problem at all.

I will test the upgrade again tomorrow and give feedback

We have Basic Support licenses for all 9 involved systems, i just did not put them into the system since we are still testing and reinstalling several times.
