First thing to do is update CPU microcode as part of BIOS/UEFI firmware update
or just OS-level CPU microcode update.

Thanks for the tip, Eugene.
However, this is a Gemini Lake processor and fs is ZFS. The PR referenced discusses Alder Lake / writing to FAT32 or UFS and specifically says ZFS
is fine. Would that microcode update apply in this case?
In fact, what I've done is recompiled the kernel from local releng/14
GENERIC source and have just rebooted to that a short while ago. The
previous kernel with the panics was the 14.3-RELEASE-p2 kernel from freebsd-update. Boot details from that kernel below.
