I have just got back to this. Somehow, it seems that the iso file
that I downloaded (twice?) was truncated:

$ ls -lh devuan_ascii_2.0.0_i386_desktop-live.iso*
-rw-r--r-- 1 ael ael 1005M Jun  6 23:44 devuan_ascii_2.0.0_i386_desktop-live.iso
-rw-r--r-- 1 ael ael  977M Jul 12 21:37 
devuan_ascii_2.0.0_i386_desktop-live.isofail

997M rather than 1005M. As you will gather, I have now successfully
downloaded a complete file. I used wget: I have never known that to
fail, so I have no idea what happened. Maybe some proxy/cache had a
truncated copy which might explain why the same thing happened twice.

I noted a kernal bug/message. I have now found how that was
triggered: it is reproducable. I usually loop-mount iso images as a 
check before using them. That is what triggers the dmesg dump:

# mount -o loop -t iso9660 
/store1/ael/devuan_images/devuan_ascii_2.0.0_i386_desktop-live.iso /testmnt/

The contents of /testmnt look OK. The bug seems to be around the kernel
hung_task_timeout. But you will still like the fact that systemd is
involved. But I have to admit that I have seen a kernel timing bug on
this Clevo board before (reported to both debian and the proper KML, but
with no response).

When I have a little more time, I expect to report this problem, maybe
to the same bugs. But the main point is that it seems not to be 
devuan specific.
