Public bug reported:
Using the Ubuntu flash installer from
http://people.canonical.com/~dannf/ubuntu-s390x-flash/
to prepare an Ubuntu system.
I tried to use the flash installer to prepare my Ubuntu system. I did
not get the installer to sucessfully recognize the target disk which is
a DASD. I tried both version 1.0 and 1.1 of the flash installer and
tried to run it on an already installed Ubuntu 16.04 system and on a
SUSE SLES 12 system.
Device EA80 should become the new flashed disk.
Note the two different error messages when providing the disk by bus ID
or by device file.
