Created attachment 292429 [details] Full journalctl log from startup to shutdown Reconfiguring my sound card to add the hint `jack_detect=false` via a udev rule causes a general protection fault in the kernel. This doesn't happen if I remove the udev rule.

Whoops -- this submitted before I finished writing it. Hardware: Onboard audio controller of ASRock X570 Pro4. I believe this is a Realtek ALC1200. /sys/class/sound/hw*/chip_name reports ALCS1200A
Could you give the full dmesg output? Also it'd be great if you can decode / point out the actually bug RIP (device_del+0x1bc/0x3f0).
> Could you give the full dmesg output? I thought that was all included in the journalctl log under "kernel" -- see attachment 292429 [details]. Is there something else I'm missing? > Also it'd be great if you can decode / point out the actually bug RIP > (device_del+0x1bc/0x3f0). I'm not sure how to do that. Are there instructions somewhere you can point me at?
Indeed, I overlooked the very first line :)
*** Bug 208747 has been marked as a duplicate of this bug. ***
Sorry for the late update. I finally had time to debug this problem. Below two patches are the fixes. The first one was submitted, and another one will be submitted soon. Both should be merged in 5.11 kernel, later backported to stable.
