# Troubleshooting: Linux Firmware & ROCm
|
|
|
|
## 🚨 CRITICAL WARNING: linux-firmware-20251125
|
|
|
|
**Date:** 2026-01-08
|
|
|
|
AMD pushed an update to `linux-firmware` (included in version `20251125`) that critically breaks ROCm functionality on Strix Halo systems. While this update has been recalled, many distributions (including Fedora) have not picked it up.
|
|
|
|
If you are on this firmware version, you will likely experience **instability, crashes, or arbitrary failures** with ROCm workloads.
|
|
|
|
### How to check your version
|
|
|
|
```bash
|
|
rpm -qa | grep linux-firmware
|
|
```
|
|
|
|
If you see `linux-firmware-20251125` or similar, you **must downgrade**.

## Downgrade Instructions (Fedora)
|
|
|
|
The recommended stable version is `20251111`.
|
|
|
|
### Fedora 43
|
|
|
|
```bash
|
|
# 1. Download the stable firmware packages
|
|
wget -m https://kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc43/noarch/ -I /packages/linux-firmware/20251111/1.fc43/noarch/
|
|
|
|
# 2. Navigate to the download directory
|
|
cd kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc43/noarch/
|
|
|
|
# 3. Downgrade
|
|
sudo dnf downgrade *.rpm
|
|
```
|
|
|
|
### Fedora 42
|
|
|
|
```bash
|
|
# 1. Download the stable firmware packages
|
|
wget -m https://kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc42/noarch/ -I /packages/linux-firmware/20251111/1.fc42/noarch/
|
|
|
|
# 2. Navigate to the download directory
|
|
cd kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc42/noarch/

## Kernel & Modules Check
|
|
|
|
After downgrading firmware, ensure your kernel and modules are consistent. You may want to reinstall/upgrade the kernel to ensure initramfs is rebuilt correctly or simply to match the tested configuration.
|
|
|
|
```bash
|
|
sudo dnf install kernel-6.18.3-200.fc43.x86_64 kernel-modules-extra-6.18.3-200.fc43.x86_64 kernel-tools-6.18.3-200.fc43.x86_64 --enablerepo=updates-testing
|
|
```
|
|
*(Adjust kernel version numbers as appropriate for your specific distribution state)*
|
|
|
|
Finally, **reboot** your system:
|
|
|
|
```bash
|
|
shutdown -r now
|
|
```
