So, might also be NVMe related. Other people with NVMe SSD's complain about this problem too. Not sure.
Yes, this is a possibility. But, as the shutdown/restart error is a plague that's following me since last 7 months and all the versions of El Cap, I've also tried (with 11.4) to mirror my NVMe boot disc to a brand new SSD and nothing changed. The error was still there.
I'm not saying I'm happy of the generic NVMe driver because as others pointed out already it's never been updated and it's one of the worst implementation of NVMe protocol. But presently it's the only one.
I've also tried to find the right PCI riser card for Apple iMac NVMe discs, as I thought it could be a (not cheap!) way to solve the problem, but at the moment I haven't found the right card yet.
One of my suspects on what causes the shutdown/restart error is towards the specs of some motherboards: you, I and many others among those who has experienced this error, have in common the fact we choose motherboards that have Intel USB 3.1 / TH 3 chip on them . Which are not currently supported, while who chooses motherboards with plain (Asmedia) USB 3.1 controller, more often do not have this error. It's only a speculation, though.
