The scan is forced to be done synchronously, however the ipr driver is
available and is loaded much earlier in the install process, thus it
should not significantly affect the overall install time.
One may be able to notice the difference a bit more with a fully-
automated preseed install.

In light of comment #51 above, I shall pursue uploading a udev-udeb with
modprobe.d config snippet that forces scsi_mod.scan=sync.

So my current feelings about this are as follows:
udev-udeb should ship /lib/modprobe.d/ directory
It should contain systemd.conf, just like the deb udev package, which
sets bonding max_bonds=0 and dummy numdummies=0.
It should also contain scsi-scan-sync.conf that that sets `options

Can somebody please test that booting d-i with `scsi_mod.scan=sync` on
the kernel command line, on the previously affected system, makes IPR
discovery work as expected, by the time one reaches the partitioning

Two things.
SCSI_SCAN_ASYNC=y is set from xenial to bionic.
If we believe this is what is causing the race here, we can try booting
d-i with a kernel parameter 'scsi_mod.scan=sync' specified. (or i can
rebuild d-i with such kernel cmdline built-in if required). And check if
that helps to resolve

It sounds like the root cause of this bug, then, is that the ipr driver
is taking longer than normal / longer than reasonable to
initialize+scan. If this is a regression vs. previous Ubuntu releases
(as opposed to, say, an instance of failing hardware on a particular
test machine), then we need to

scsi-modules are not in d-i's pkg-lists/netboot .cfg files. So ipr.ko is

It looks like some parties can reproduce this situation, but other cannot.
Please can you also investigate into any potential differences in these
obviously two environments?
Are both using the same or different:
- Power hardware
- adapter hardware revision
- firmware on the adapter
- 18.04 instal
