I think the bug on the FreeBSD-side is that these messages spam repeatedly
every few seconds and they clobber the main console, making using the
boot/install console unusable.  Some searching around, it looks like when Linux
encounters these errors, they are at least stuffed away in the dmesg log and
don't flood the console.  I can't tell if they repeat forever in dmesg, though.
 Haven't actually tried booting Linux on this laptop yet (I have enough systems
running Linux to keep me entertained as-is).

If the console could be fixed, I might be able to at least install BSD on it
and see how it holds up.  As for fixing the BIOS/UEFI/ACPI issues directly, if
anyone has contacts at HP I can go and pester, I'll give it a shot.  But I did
not buy the CarePack for this thing, so going through their normal support
channels would be a futile effort.

Google did turn up this post on the FreeBSD forums that I hadn't come across
before:
https://forums.freebsd.org/threads/panic-when-connecting-or-disconnecting-a-c-power.81550/

Which points at amdgpu being somewhat responsible.  So if this is thermal
zone-related, possibly tied to the graphics adapter, and thus, the
drm-kmod/gpu-firmware packages?

Push comes to shove, I'll donate it to goodwill and hunt down a non-HP laptop
that'll be more....compatible.
