 With the patch, I'm still getting coredumps.  This time, the root file
 system resizing step did not happen, but I did get a login prompt:

 I was able to log in, and the login shell works, but if I try to run a
 subshell from it, the subshell dumps core.  Many other commands, such
 as ls or ps, also dump core.  The ls and ps in /rescue do work.

 I'm not using nfs, but I managed to get some core dumps (after
 remounting the root file system r/w) and saved them by removing the
 embedded USB flash drive from the erlite3 and reading it on another
 system.  You can find them in
 
   https://www.gson.org/netbsd/bugs/erlite3/cores.tar.gz
 
 I have not looked at them myself yet.
