Comment 3 for bug 1928393

Before we revert we should see if newer firmware fixes the issue, and make sure we are only changing the specific firmware files for your hardware.

I think your hardware is the "Picasso" series. Can you try the following? If you are unsure about any of the following steps, let me know and I can provide you with test packages to install instead.

Save all files matching /lib/firmware/amdgpu/picasso* from linux-firmware 1.190.5. Reinstall 1.197, then overwrite the picasso firmware files with the ones you saved. Reboot, and confirm that the issues you see with 1.197 are fixed. If they are not fixed, then there's no need to proceed as we haven't found the correct firmware files which are causing your issues.

Then please download the picasso firmware files from here:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amdgpu

Use the "plain" link next to each file to download the file. Overwrite the files in /lib/firmware/admgpu with these files, reboot, and see if you continue to have problems.
