OVERVIEW
After booting, device files like /dev/nst0 for a DDS3 HP C1537A scsi tape drive
attached to a pci Adaptec 2940 SCSI adapter are missing.
STEPS TO REPRODUCE
boot.
ACTUAL RESULTS
/dev/nst0 is not present.
There is an error message in the journal:

upon issuing "lsmod", kernel module "aic7xxx" is listed, but module "st" is
missing.
EXPECTED RESULTS
/dev/nst0 should be present, kernel module "st" should be loaded.
BUILD DATE & HARDWARE
opensuse leap 42.3 with all patches / updates on x86-64 hardware (asus z170-a
with intel i5-6600).
ADDITIONAL BUILDS AND PLATFORMS
no such bug in opensuse leap 42.2 on Jan 14, 2018 with all paches / updates on
the same machine.
ADDITIONAL INFORMATION
adding the following 2 lines to /etc/init.d/after.local "fixes" the problem:
modprobe -r aic7xxx
modprobe aic7xxx
this produces the following output in the system journal:

wriede Exp $
probably, one could blacklist module aic7xxx in /etc/modprobe.d/99-local.conf
and, thus, omit the command "modprobe -r aic7xxx" above. with the current
setup, however, i can monitor whether the bug persists or not.
