[-- Attachment #1 --] Hello dear FreeBSD community, Recently I tried to boot from FreeBSD 14-ALPHA2 image and got panic on first boot after power on. My hardware is AMD Ryzen 9 5900X on ASUS ROG STRIX B550-E GAMING. It's related to audio chip ALC1220 initialization. If I remember correctly, when I tried FreeBSD 13-STABLE, around 2 years ago, no panic was observed. But at that time my GPU was unsupported by drm-kmod. So I installed Linux and used it for 2 years. On Linux, no such a panic observed. Now drm-kmod supports my GPU and I want move to FreeBSD. Also tried 13.2, got the same panic. Can't try earlier FreeBSD 13 releases, as they are not available for download anymore. I found two related bug reports: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=264305 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=268393 My backtrace is the same as in reported issues. So I did not write it from a screen to a paper. As I understand, this bug affects all AMD Zen2, Zen3 and Zen4 computers and laptops. We are near FreeBSD 14.0 release now, maybe it will be possible to fix it before release. Thanks.
