The machine was still running, but I could not get access to any terminal to 
check the problem. When I booted to single-useer mode and then tried to start X, 
it failed but logged no useful errors.

I do not know which patch fixed the problem, but a pull of drm-intel-next-queued
handled the problem. My system is now booting fine. I think we only need to 
worry about the coronavirus,

I did have one trivial merge conflict to fix.

Thanks for your help.
