This is a stuck GPE. This board in particular is a known issue; search
the lists.

mbuhl@ suggested a few months back that I get one of these machines to fix
the issue, but when I started looking at it, the simplest fix was to just
install a new bios.  Since this is likely one of these super cheap 4 port
igc(4) aliexpress "firewall PCs", you may need to search a bit to find a
compatible bios since most of these don't have a real brand site associated
with them.

FWIW, the machines with "techvision" bios (like yours) exhibit this issue.
Mine had techvision bios (and the same problem) before I flashed it to the
image described below.

You need to find this bios:

bios0: vendor American Megatrends International, LLC. version "JK4LV107" date 
04/17/2023

I just found this Reddit Post [0], describing a related issue with thiskind of board. There's also a download link [1] in the comments for thebios update. As soon as I found some time I will install the update.Thanks!

That one works on my machine, with exactly the same config as yours. No
more ACPI GPE storm.

I don't have the link anymore for where I found the BIOS image, but I
think it was on servethehome in one of the long threads about these
machines. You need to do some digging.

While the root cause may be due to us lacking some driver for the device
owning that GPE, or our lack of activating GPEs based on attached
hardware, the 5-minute bios update fix was a good enough fix for me and
I moved on to other things.

The other lesson I learned is that you get what you pay for; buying $100
PCs from aliexpress means you're just going to be paying for it somewhere
else. In this case, dealing with shoddy engineering and unsupported boards.
