Comment 23 for bug 1794477

I can see the Mellanox devices with that 4.17.0-1001-azure kernel.

I installed the new kernel:

sudo dpkg -i linux-modules-4.17.0-1001-azure_4.17.0-1001.2~lp1794477_amd64.deb linux-modules-extra-4.17.0-1001-azure_4.17.0-1001.2~lp1794477_amd64.deb linux-image-unsigned-4.17.0-1001-azure_4.17.0-1001.2~lp1794477_amd64.deb

Fixed the missing depencies with:

sudo apt --fix-broken install

Updated grub just in case:

sudo update-grub

I rebooted and I see the devices:
