Output of 'acpidump -dt'

Attempting to boot the FreeBSD 13.0-RELEASE-p0 installer memory stick on an HP
ProBook 455 G7 laptop running the latest firmware/BIOS release (S79 v01.06.00)
usually gets to the installer greeting (sometimes reboots in the middle of
booting, but works second time around; different bug).  However, within several
seconds, the following ACP error messages start spamming the screen once every
2-3 seconds:

Firmware Error (ACPI): AE_AML_PACKAGE_LIMIT, Index (0x000000005) is beyond end
of object (length 0x5) (20201113/exoparg2-569)
ACPI Error: Aborting method \_TZ.GTTP due to previous error
(AE_AML_PACKAGE_LIMIT) (20201113/psparse-689)
ACPI Error: Aborting method \_TZ.CHGZ due to previous error
(AE_AML_PACKAGE_LIMIT) (20201113/psparse-689)


I bought the laptop as a custom build in late 2020, but never really did
anything with it because of these ACPi errors on FreeBSD 12.2-RELEASE media. 
Finally got around to trying 13.0-RELEASE media, and getting the same error. 
Doing a Google search for portions of these error strings returns a lot of
similar errors on Linux distributions, but no real resolutions, other than
complaining to the manufacturer.  I am not going to bother with that because
I'd be surprised if they did anything about it.  The system came preloaded with
a FreeDOS release.

I gave a quick test of 14.0-CURRENT cut from 9aa29457d55 (r249761), and that
doesn't even boot all the way, crashing into the kernel debugger due to a page
fault panic on.....it looks like the audio driver.

I am including as attachments the output of 'acpidump -dt | gzip -c9 >
foo.asl.gz', just renamed and compressed with XZ.  Also attached a screenshot
showing how messy the primary console is with these ACPI errors repeating every
few seconds.

If anyone thinks this is fixable, I can try testing things, but will probably
have to wait until a later 14.0-CURRENT snapshot, or someone will need to
provide modified copies of 13.0-RELEASE GENERIC kernels that I can kludge onto
this thumb drive I am booting off of.  Assuming the bug is in the kernel...
