Hey everyone, I'm on Fedora 31 and recently upgraded my kernel from 5.3.16 to 5.4.7, and now my sound (via snd_hda_intel) and wifi doesn't work; the wifi options in GNOME are missing, and my only sound device is the default PulseAudio "Dummy Output". Everything works fine if I manually select the old kernel in GRUB. Is this a known issue, and should I file a bug about this? # dmidecode -s system-version ThinkPad X1 Carbon 7th Here's the relevant log sections: Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if info 0x040380 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: Digital mics found on Skylake+ platform, using SOF driver Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: warning: No matching ASoC machine driver found Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: DSP detected with PCI class/subclass/prog-if 0x040380 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: use msi interrupt mode Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: hda codecs found, mask 5 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: using HDA machine driver skl_hda_dsp_generic now Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: Direct firmware load for intel/sof/sof-cml.ri failed with error -2 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: error: request firmware intel/sof/sof-cml.ri failed err: -2 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: error: failed to load DSP firmware -2 Jan 08 16:42:46 newton kernel: sof-audio-pci 0000:00:1f.3: error: sof_probe_work failed err: -2 Jan 08 16:42:47 newton kernel: iwlwifi 0000:00:14.3: Collecting data: trigger 15 fired.
