The propagation of kernel 4.16.12 from Sid to Buster has greatly improved this situation, i.e., no lock ups so far (uptime approaching 3 days since I switched to 4.16.12 from 4.16.5) and may have completely solved it. [...]
Well, further experience showed lockups occurred roughly as often for 4.16.12 as for 4.16.5. So currently I am only able to use this computer in a reliable way using an X-terminal (an alternate computer with a different X server that runs "X -query <name of this computer>" to control and display remote desktop results that are running on this computer). Therefore I plan to wait for kernel 4.17.x (which apparently has many graphics fixes for modern AMD cards such as the RX 550) to propagate to Buster before I try this computer again with a local X server, i.e., direct use rather than X-terminal use.
