elevate on Gen 8 HP Enterprise Servers goes wrong

Hello, So we run elevate on a bl460c Gen 8 server, there was no warning, no blocker not even a warning info. It was being elevated to AlmaLinux 8. It reached to level 4 and then stopped. The reason behind this was that the server no longer could see NIC's after the update. The server already had the latest HP Service pack so it was something else. Apparently, someone thought it was a good idea to remove the NIC drivers on Centos 8. Don't despair there is a solution. Before you start the installation or afterwards download this rpm to this GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet intel_iommu=on intremap=off" after you do so, if your server is uefi execute grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg if its not uefi then execute this instead grub2-mkconfig -o /boot/grub2/grub.cfg and reboot I am still puzzled that not many people have complained about it and its not that these machines are old. GEN 8 or (8.1)Servers are still very capable machines.
