Intermittent kernel panic on boot?

ratemisia · 2024-11-17 03:14:44

My first post in the Newbie Corner! I'll explain what's been going on:

I've recently done a fresh Arch install on my work laptop, using the latest install media. Unfortunately, I've had a lot of trouble with that media in these last couple weeks...
First, I ran into an issue where archinstall would crash if I chose to install a sound server, but followed advice on the GitHub at Issue #2764 to install one manually after I booted into the system.
This got me through the initial install, but no joy after manually installing pipewire: I still get only a Dummy Output audio device, and no sound.
Following this post, I ran

sudo dmesg | grep -iE 'snd|sof'

and found from error messages therein that I was missing the

sof-firmware

package! Installing that, I restarted my computer - but not only did I still not have sound, I realized that I was now having kernel panic messages on boot.
Running

pacman -Qk

I saw that pipewire and some related packages seemed to be broken. I reinstalled every package on the list, which made all problem items disappear from that pacman check.
Good! But as of right now, I still don't have sound on my system, and I get that kernel panic every two or three times I reboot my machine. I've been able to boot so far by using the fallback ramdisk image or just retrying a few times until it works... which has made it all the more confusing to troubleshoot, since it's not a reliable failure.

I'd be happy to run any commands and provide any information you'd like. Hoping someone more knowledgeable than me will be able to guide me to a fix!

Take a picture of the kernel panic.
Post the output of

sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v backup

As for the sound

amixer -D hw:0
sudo fuser -v /dev/snd/*
pactl list sinks
pactl list sink-inputs

Can you "mpv -ao alsa thunderstruck.mp3"?

Firstly for
sudo LC_ALL=C pacman -Qkk | grep -v ', 0 altered files' | grep -v backup

filesystem: 124 total files, 1 altered file
intel-ucode: 159 total files, 1 altered file
shadow: 588 total files, 1 altered file
spotify: 153 total files, 110 altered files
systemd: 1547 total files, 1 altered file

And for the sound... I don't seem to have mpv installed, so I haven't been able to test as requested, but when I turned that laptop on this morning, my audio devices sprung to life. Strange, but welcome. I'll reboot a few times and try to reproduce the kernel panic for you.

I am wondering about the boot to boot variation. Just a hunch, can you please post your /etc/fstab file?
