Handling regression in linux-firmware & amd_gpu

[Aravisian]

@Nourpon

Hello,

It come from the linux-firmware update who get regression for AMD GPU
Remove your grub options and try to downgrade :

sudo apt install linux-firmware=20240318.git3b128b60-0ubuntu2.26

then mark linux-firmware as hold

sudo apt-mark hold linux-firmware
apt-mark showhold #you should see linux-firmware in the list

the regenerate initramfs with the good firmware :

uname -r #your actual kernel should be the output
sudo update-initramfs -u -k 'the result of uname -r'
sudo reboot

The above is @Nourpon's simple solution to Ubuntu's misaligned linux-firmware package affecting AMD GPU users.

I have an Intel I7 does that fix apply and its quite complex to run

[Nourpon]

it's about GPU not about CPU, you have an AMD GPU

[JimFinis]

It mentioned Ryzen 7

Black screen with AMD 7500 video card

I'm unable to get my video card to work for the last 4 days have been getting help from google chat box lost hrs and hrs actually at least 3 days Can someone please help I can get into system via safe boot using ctrl+alt+f2 I've been struggling with the system basically since I installed, initially had a Nividia card then was told that and AMD card would be best, I purchased a Rodeon rx 6500 xt card, had issues getting it to work with help Chat bot in the last week or so lost printers then rei…

so you have AMD 7500 GPU or not ?

Apologies I've and AMD Radeon RX 6500 XT

[Nourpon]

don't apology, I was just lost
So this fix could concern you

[JimFinis]

After spending the better of 3 days with the help of a gemini Chat bot finally came to the conclusion to reinstall the system files reformat the / partition, I have a 1tb NVME drive installed and partitioned in 2 so my home partition was on the nvme0n1p2 which saved me having to reformat, to cut the long story short I am now back in business using 7.0.0-31 kernel.
Now I don't if that is the correct kernel to use the amd Radeon RX 6500 XT seems to be ok not sure for how long any suggestions would be welcome
I do have another issue though with printing and I'll log another case for that

[Nourpon]

The problem is not the kernel ! but linux-firmware, so if you don't encounter black screen again you are lucky

There was published a Firmware Update for AMD now:

The Link shows the Details:

Bug #2166531 “[SRU] Update DCN 3.5 microcode to match DCN 3.6 mi...” : Bugs :...

Yep saw that this morning. didnt see much change after reboot tho

[Nourpon]

Yeah, for now I will test few days before I'm sure it work and like that people who "hold" linux-firmware to stay in 2.26 will know they can install the full linux-firmware spltited version

[Nourpon]

After updating and this since few days, I can say you can upgrade, to do it you just have to unhold linux-firmware package and launch an upgrade:

sudo apt-mark unhold linux-firmware
apt-mark showhold #you shouldn't see linux-firmware in the list anymore
sudo apt update && sudo apt upgrade
apt-cache policy linux-firmware-amd-graphics

You should see this at the end
