Glad I saw this before trying a freshly-built 4.14 with a few more
kernel config options enabled per the README file for systemd.  Doesn't
mean there isn't a systemd/udev issue as well, but if the firmware for
the SCSI controller isn't getting loaded, that makes detection of the
host and attached devices pretty much a non-starter.
