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 be looking at a kernel bug; opening a
task on the linux package for this.
Separately, based on the investigation and findings up to this point, I
think d-i should also be fixed to scan disks synchronously, because
there is certainly a race here; and given the design of d-i, which does
not automatically update the UI with details of late-detected disks, I
think it's more important to be reliable than fast.
