Yes I have and there is only 90 gap in the journal where nothing is
even recorded. What I know is when there is this hang, it's due to a
stop job waiting on the user session. I don't know why a direct
restart while still logged in appears to always result in a hang;
while log out immediately works, and subsequent restart from GDM
immediately works.
The hang within gnome-shell on a restart or shutdown request is
actually a brutal hang. I have no keyboard control, the entire UI is
locked up, I can't get to a console. This is a clean installation of
Fedora 24, it's not an upgrade.
Ergo, from my perspective, the feature of KillUserProcesses=yes
doesn't even really completely work at present. It's not solving the
problem it's intended to solve, unless I first log out and then
restart, which is sorta ick. Not quite pointless, but fairly
pointless.
