-current, UFS.

It sounds like there's some hope the trouble isn't purely local to my
machines. I'll just continue to update and hope for the best. A Pi3
running -current as well as a Pi3 running stable/13 seem to be affected.
A Pi4 running -current works perfectly. All use UFS on mechanical 
hard disks. 

FWIW, one boot attempt followed the mountroot failure
with a kernel panic and backtrace, but I inadvertently wiped 
out the console transcript before I could post it. If that
happens again I'll take more care.

Thanks to everyone who replied, especially Mark!
