At least google AI tells me this:

Spent some time trying to chase this down. I managed to set up a VM to build the VyOS image, but I can't figure out how to build the kernel. The docs appear to be outdated?

VM config in case it helps narrowing it down.

Is there a reason this commit isn't getting pulled into the nightlies? I'm looking at https://github.com/vyos/vyos-nightly-build/releases and don't see it in the changelog. Newer ISOs still won't boot.

Narrowed it down to changes between 2026.05.05-0039-rolling (sig) and 2026.05.07-0040-rolling.

Also, I'm getting error

Drivers seem to be present, but device is not even appearing in lspci. Wouldn't this be more likely due to a hyper-v driver issue than the mellanox driver?
