Well, another lockup. This time after ~ 10 days of uptime. Box was idle
at the time and just a solid freeze. This is an ASUS PRIME X370-PRO
running BIOS from 09/07/2018 (latest).? Not sure if BIOS related or OS
related. I have another motherboard (MSI) that I will install 12.0 on
and see if its any different.? There is also a micro code update from
AMD last week. However, there are no release notes as to what it
changes. I will hold off on that for now and see if I can get lockups on
the MSI in the next week or two.

I did the opposite yesterday - I updated my microcode to the latest one 
from MSI (though the AMD update it contains is from the summer I belive, 
depsite the BIOS only comming out a couple of weeks ago). Am running 
12-STABLE on there, and will see how long it lasts.

Only got to do this yesterday as havent been near the machine for weeks. 
I didnt adjust any RAM timings and left everything at the default after 
the BIOS update.

but until yesterday it has locked up about every couple of days :-(

-pete.

Here's another datapoint: No lockups/problems with:

AMD Ryzen Threadripper 2950X
Board: PRIME X399-A (not the -PRO)
BIOS from 10/12/2018
running: 13.0-CURRENT r340445
up 19 days, running as a package builder
