Looking at the logs, I found “Watchdog0: Watchdog not shutdown”
I found a solved bugzilla that addressed demicode for intel I7’s – of which I have i7-5930K CPU @ 3.50GHz
Long story made short:
I searched Yast for “microcode”
and did a forced update to
Leap 42.1 is now ripping right through shutdown and reboot
We’ll see what happens at the next update!
