These errors are not kernel panicks, they are just that systemd units
are not starting and the programs that  are executed in the unit files
are returning these errors such as the 203 with no other explanation.  I
tried for instance to run /usr/bin/postgresql-9.4-check-db-dir and it
said that postgresql.conf was missing, but I could do an ls on that file
and got the name.  I think I have more like that, but no kernel errors
and scrub has no errors.  Should I go back to an earlier btrfs progs
and, if so, which one?
