There are a dozen of like firmware missing for amdgpu and nvidia cards while doing the update-initramfs -u command

Have you tried with a weekly image which will have a newer kernel? Do you have more of an error message? Unfortunately, the Kali team isn't large and we don't have every piece of hardware available in order to test, so we need users help when they are running into hardware issues.

And the firmware missing isn't always an issue, if you don't have those devices, then it not being there just means that it's not taking up space on your drive.

This report has been filed against an old version of Kali. We will be closing this ticket due to inactivity.

Please could you see if you are able to replicate this issue with the latest version of Kali Linux (https://www.kali.org/get-kali/)?

If you are still facing the same problem, feel free to re-open the ticket. If you choose to do this, could you provide more information to the issue you are facing, and also give information about your setup?
