Comment 62 for bug 1833618

Both, upstream version and Debian version already have the following change:

commit 988e967513fc9dc2be35dcb5bbc6b888f853538f
Author: Douglas Gilbert <email address hidden>
Date: Wed May 11 17:20:52 2016

    rescan-scsi-bus.sh + 55-scsi-sg3_id.rules: fixes from HR at Suse

    git-svn-id: svn://localhost/trunk@703 6180dd3e-e324-4e3e-922d-17de1ae2f315

which fix the SERIAL issue (but not the delay in insertion caused by errors of sg_inq commands).

That will be enough for this particular case (MAAS related). I can, during the next merge (F-series) propose to upstream a change not to execute sg_inq 0x83 if 0x80 wasn't successful, but, for now, taking in consideration the phase we are for Eoan (almost freeze), I'll base the changes in the upstream commit (at least the changes for 55-scsi-sg3_id.rules changes).

Marking F-series and Eoan as "Fix Released" as they keep the serial like it should be:

Installing the version: 1.44-1ubuntu1 in Disco fixes the ID_SERIAL issue (enough for now).
