Hmm, this is certainly weird.

Any chance you can do "strace -ff -p 1 -o /tmp/someplace/log" (maybe
from the debug shell). Then, trigger the issue again, and find the
tight log file in /tmp/someplace that ends with an exit(219). It would
be good to paste that file somewhere (or at least the last few lines
which might give an indication on what precisely fails), so that I can
have a look.

Also, try booting with debug logs on ("systemd.log_level=debug") and
see if this generates any additional log output that might be useful.
