Bug Description
TLDR - Looks like the amdgpu module is included in the Jammy kernel images but not in Noble.
Hello!
I have a laptop with the AMD Ryzen 7840U CPU which has a 780M iGPU running both Jammy-based and Noble-based distro elementary OS releases.
This issue occurs only with the Noble and not Jammy edition.
Upon bootup with the "quiet splash" params there is just a blank screen and apparent hang which is prevented if I remove the "splash" option and then I get the expected login screen just fine.
Note that I ran the following command on both Jammy and Noble:
sudo lsinitramfs /boot/initrd-
And I see the amdgpu module is present in the Jammy image but not the Noble image.
So I appended "amdgpu" to the /etc/initramfs-
sudo update-initramfs -uk all
Which resolves the issue for me with Noble as well.
Note both my Jammy and Noble installs are on the same kernel version currently 6.8-xxx-40 although the amdgpu module is included in the Jammy image but not the Noble one.
Thank you!

Just a note that I just now also tried the official/stock Jammy 22.04.4 and Noble 24.04 ISOs in live sessions and observed the same thing - which is the amdgpu module is present in the Jammy kernel image but not in Noble.
I did a:
sudo lsinitramfs /cdrom/ casper/ initrd | grep amdgpu
