Mellanox drivers for Proxmox 8.2 Kernel 6.8

[Joe Botha]

Hi

I noticed when upgrading from Proxmox 8.1 to 8.2 the Mellanox drivers fail to build.

Probably because of the kernel version change to 6.8. Everything worked fine with version 6.5.

I looked at the changelog for latest Mellanox drivers, but can't see anything relevant.

Does the latest Proxmox have minimum driver version?

Error logs below. Advice for fixing this?

Hi Joe,

Is there a reason why you need the out-the-tree drivers and don't work with the mainline drivers?
I assume that the drivers are simply not yet built together with the kernel because the kernel is too new and will only receive support for the new kernel with an update

Until then, you could pin the old kernel 6.5
