Can't restart systems with 2400G + AMD Drivers

I have 9 identical systems as follows:

 

Ryzen 5 2400G

8G (2x4G) Corsair Vengeance LPX 2400

Asus Prime B450M-A with latest flash (Dec2018)

Windows 10 LTSB v1607 <--required!

 

I have tried the 18.12.2 and the 19.1.1 driver packs with the same results.  Trying to Restart Windows causes an immediate system hang, and eventually bluescreens with DPC_WATCHDOG_VIOLATION.  Trying to Shutdown Windows causes an immediate bluescreen with VIDEO_DXGKRNL_FATAL_ERROR.  Uninstalling the Radeon Software and deleting the AMD driver makes this problem go away.  These systems are rock solid with the Microsoft generic video driver installed.  Unfortunately, that driver only supports 1 monitor at a time with this setup.  These systems are also rock solid WITH the AMD drivers, if the 2400G is replaced with a 2700 + RX570.

 

I would love for this 2400G configuration to be our current general purpose PC, if I could make it work.  Suggestions?
