dmidecode BIOS info and further debug info

I have re-occuring randomly timed freezes of my system. Some digging around
showed them to be around TLB shootdown.

Checked the logs and only found a solid hint about anything that could lead to
this behavior. This is a BIOS related problem.

The freeze can happen at a day after working properly, or even as a worst case
scenario within 20 minutes. Usually the case is about a day.

Setup info:
Ryzen 7 1700
Fatal1ty X370 Professional Gaming
Trident Z RAM (16GB) (Non ECC)

I have the following hard drives: 7 4Tb WD Red (from the CMR era I am more
confident than not from their part numbers).

The system is running from a USB flash disk.

I am running BIOS version 5.10 as per an Asrock support answer, which stated
not to update any further because of my CPU.
The before mentioned BIOS related error (and only one found) is this:
Firmware Warning (ACPI): Optional FADT field Pm2ControlBlock has valid Length
but zero Address: 0x0000000000000000/0x1 (20171214/tbfadt-796)

When the freeze happens nothing else than a hardware reboot is working.
Software shutdown from the button is not working.

I am willing to supply needed logs if asked for.

I also attach a dmidecode info file and any debug files I could include. 
My problem seems to heavily align with this problem from the mailing list:
https://lists.freebsd.org/pipermail/freebsd-stable/2017-May/087162.html
I cannot update to a newest BIOS though as stated before, so its solution
cannot be applied.
