Comment # 25 on bug 903560 from grant k

Understood.

And, I am able to simply & consistently reproduce the problem on (currently) 3
different machines.  In all cases, systemd v210 fails to shutdown correctly,
v208 does not.

Whether the causal difference is software &/or hardware environment, I've no
idea yet.

The tests above that excluded the majority of hw & drivers
(https://bugzilla.opensuse.org/show_bug.cgi?id=903560#c15) suggest that it may
not be hardware.

It's clear the issue involves systemd.  Whether that's a primary, or secondary,
involvement, I don't yet know.

Since Opensuse 13.2 ships with v210, and, IIUC, it has no available option to
downgrade to v208 -- assuming that it's 'just' systemd version dependent --
upgrade to 13.2 poses a risk that similar machines will have these shutdown
issues -- with no available fix/fallback.
