After updating my Fedora 42 system, my AMD GPU is failing to load the firmware isp_4_1_0.bin, even though a newer version isp_4_1_1.bin is available in the correct firmware directory. The system repeatedly reports:

amdgpu 0000:66:00.0: amdgpu: [drm] Optional firmware "amdgpu/isp_4_1_0.bin" was not found

Despite manually extracting isp_4_1_1.bin.xz and creating a symbolic link, the issue persists.

Below are all the commands I ran in an attempt to fix the problem:

:keycap_1: Confirming the Firmware Location

ls /lib/firmware/amdgpu/ | grep isp

Result:

isp_4_1_0.bin
isp_4_1_1.bin.xz

The latest isp_4_1_1.bin.xz is present.

:keycap_2: Extracting and Renaming the Firmware

sudo mv /lib/firmware/amdgpu/isp_4_1_1.bin.xz /lib/firmware/amdgpu/isp_4_1_0.bin.xz
sudo unxz /lib/firmware/amdgpu/isp_4_1_0.bin.xz

Now isp_4_1_0.bin should exist, but the system still fails to detect it correctly.

:keycap_3: Forcing the Kernel to Load the Correct Firmware

echo "options amdgpu firmware_load_type=2" | sudo tee -a /etc/modprobe.d/amdgpu.conf
sudo dracut --force
sudo reboot

No effect—the system still reports isp_4_1_0.bin not found.

:keycap_4: Creating a Symbolic Link for the Missing Firmware

sudo ln -sf /lib/firmware/amdgpu/isp_4_1_1.bin /lib/firmware/amdgpu/isp_4_1_0.bin
sudo dracut --force
sudo reboot

No effect—system continues searching for isp_4_1_0.bin instead of recognizing the latest version.

:keycap_5: Checking Kernel Logs After Each Attempt

sudo dmesg | grep -i isp
sudo journalctl -b -p err

Same error persists:

amdgpu: [drm] Optional firmware "amdgpu/isp_4_1_0.bin" was not found

:keycap_6: Attempting to Reinstall the AMD Driver

Finally, we tried completely removing and reinstalling the AMD driver:

sudo dnf remove xorg-x11-drv-amdgpu amdgpu-firmware
sudo dracut --force
sudo reboot

sudo dnf install xorg-x11-drv-amdgpu amdgpu-firmware
sudo reboot

Issue still persists.

Expected Behavior vs. Current Behavior

Expected:

• Fedora 42 should automatically detect the newest firmware version (isp_4_1_1.bin) or, at the very least, load isp_4_1_0.bin after it is extracted.

Current:

• The system continues to search for the missing isp_4_1_0.bin, failing to recognize that isp_4_1_1.bin is available.

Possible Causes & Questions for AMD Developers

1. Is isp_4_1_1.bin supposed to replace isp_4_1_0.bin, or is it an independent version?

2. Does the AMD Linux driver need an update to recognize the latest firmware?

3. Can we manually specify which firmware to load? If so, how?

Seeking AMD Support & Fix

Since we've tried all possible local fixes, this issue seems to be a driver-level or firmware recognition bug. Can AMD confirm if:

• The latest isp_4_1_1.bin is officially supported?

• A driver patch is needed to detect it correctly?

• A manual override method exists to ensure the correct firmware loads?

Thank you for your time! Looking forward to any guidance or fixes that might resolve this issue.
