Hi everyone,

After a recent kernel update (6.15), I’ve encountered several issues:

  1. Wi-Fi and Bluetooth have stopped working entirely.
  2. During boot, the system briefly displays a strange gray screen before reaching the login panel.
  3. Front panel audio doesn’t work unless I first plug headphones into the rear audio jack, then reconnect them to the front jack.

I’d like to report these issues with more detailed system information and also get help troubleshooting them. Where is the best place to file such a report? And are there recommended steps to gather relevant logs or diagnostics for this kind of hardware-related problem?

Thanks in advance!

Got Wifi and Bluetooth working via a hard reboot (shutting down and disconnect it from power outlet). Sometimes they tend to go away for a while :confused:

And weirdly enough some rare visual artifacts prior to login screen and when shutting down/rebooting also disappeared.

and finally the dmesg errors for amdgpu seem to be a problem of linux-firmware. And is affecting other platforms, I tried other distro live images w/ different kernel versions

The front audio jack problem persist which is weird as in windows it doesn’t happen

I solved the problem by downgrade the packages:
alsa-lib 1.2.14-3.fc42 → 1.2.13-4.fc42
alsa-sof-firmware 2025.05-1.fc42 → 2025.01-1.fc42
alsa-ucm 1.2.14-3.fc42 → 1.2.13-4.fc42
alsa-utils 1.2.14-3.fc42 → 1.2.13-4.fc42

Even though I haven’t found the reason, I’m still avoiding updating these components for now.

Thanks, this solved the problem for me too

Glad to be helpful.
I’d add that, upon further investigation, the
alsa-lib
alsa-sof-firmware
packages do not require downgrading.
It seems the problem is caused by changes to the alsa-ucm package, specifically:

  • changes to the configuration files for “HiFi” vs. “Pro Audio” devices
  • new rules for automatic headphone/speaker switching
