# 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
|
|
mkdir -p ~/linux-firmware-downgrade
|
|
cd ~/linux-firmware-downgrade
|
|
|
|
wget -r -np -nd -A '*.rpm' https://kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc43/noarch/
|
|
|
|
sudo dnf downgrade ./*.rpm
|
|
sudo dracut -f
|
|
```
|
|
|
|
### Fedora 42
|
|
|
|
```bash
|
|
mkdir -p ~/linux-firmware-downgrade
|
|
cd ~/linux-firmware-downgrade
|
|
|
|
wget -r -np -nd -A '*.rpm' https://kojipkgs.fedoraproject.org/packages/linux-firmware/20251111/1.fc42/noarch/
|
|
|
|
sudo dnf downgrade ./*.rpm
|
|
sudo dracut -f
|
|
```
|

## Important: Kernel & Initramfs
|
|
|
|
**Crucially, `dracut -f` MUST be run with the kernel you intend to boot.**
|
|
|
|
By default, `dracut -f` regenerates the initramfs for the *currently running* kernel. If you are not currently running the kernel you intend to use (e.g. you just installed it but haven't rebooted, or are booting into an older one), you must specify the version explicitly.
|
|
|
|
All tests have been validated with kernel: **`6.18.4-200.fc43.x86_64`**
|
|
|
|
To regenerate for a specific kernel (e.g. the tested one):
|
|
|
|
```bash
|
|
sudo dracut -f --kver 6.18.4-200.fc43.x86_64
|
|
```
|
|
|
|
Finally, **reboot** your system:
|
|
|
|
```bash
|
|
shutdown -r now
|
|
```
