Mark this SOLVED (partially): software problem.

dpkg continued to kill the system trying to setup 
linux-headers. I discovered that dpkg will purge the 
linux-headers package and then I can try installing again. 
On one try I was running pg on dkms in an attempt to see 
what was going on that killed the machine. Two times I got a 
long screen full of tasks running various types of cc just 
before the crash.

I set up my pg to repeat every few secs and spooled the 
output to a file. Then I started a tail on that spool file. 
Surprise!! It ran to completion!

Here is my analysis: I have a big system. An AMD 8 core 
Ryzen running at 3.8GHz with 64GB of memory. I think that 
without any other load on the machine some task is getting 
started before it should and either steps on a task that 
should have finished by that time or can't find something 
that was supposed to be created by a task that hasn't run 
yet. It has to be something serious because all the 
screens/sessions are cleared and the system is frozen. I 
have to use the reset button to re-start and once or twice I 
have had to cycle the power to get re-booted.

No progress on other problems. I will open other threads for 
them.

Thanks for the comments. They got me thinking!
