Did that, and got a dmesg.boot. I also was able to get a dmesg.boot from a soft
reboot with SMP enabled, which I'll also attach.

For other operating systems, I tested Windows 7, 8.1, and Xubuntu 24.04, and
those are fine on this machine. I would test more, but Ventoy either doesn't
boot the OS or the OS doesn't let me install it to the drive when booted with
Ventoy, idk why.

> The fact that you are only getting that panic sometimes is very odd.  It means your firmware is not always generating that table.

What I meant to say was it either gives the kernel panic or the OS freezes
before it can give it. It doesn't sometimes boot. I could test w2k in MPS mode
by attaching a DVD drive and seeing if that works. I'll do it if I don't feel
lazy.
