Public bug reported:

When installing Ubuntu 22.04 via local USB or thru remote Virtual Media
in UEFI mode, the VGA console display will displays black screen after
"Enter" key is pressed to install Ubuntu OS server from grub menu.

In Legacy/BIOS mode, everything works normal as expected.

Here are the steps to reproduce:
1. Install fresh Ubuntu 22.04LTS server edition (or even 20.04LTS server 
edition) on AMD (4th Gen EPYC) system that has NVidia H100 GPU over an Ubuntu 
bootable USB stick or thru Virtual Media mapped to an ISO image on a remote 
file server
2. When the Ubuntu installer menu appears, press the keyboard Enter key, then 
the monitor will goes to black screen

Actual results:
The monitor screen will stay in black screen once installation of Ubuntu 22.04 
has started after pressing the enter key on the grub menu. 

Expected results:
The VGA monitor should display normally as expected during imnstallation and 
the server will bootup with the OS installed successfully.  

Additional info:
- The symptom does not manifest under BIOS legacy mode. Installation works fine 
with no problem.
- The symptom does not appear If H100 GPU is removed from the server
- The issue is only evident in AMD server with GPU and there's no problem with 
Intel based GPU server
- Tried adding nomodeset in the kernel bot parameter, but problem persist 
- Tried kernel 5.15.0-83-generic and 6.2.0-33-generic as mentioned in the bug 
report #1968519 on 2022-04-11, problem remains
