Ugh, tab key did a submit! Launchpad needs some work.
So, in summary:
- with "acpi=off noapic", all kernels can reboot but hang during shutdown
- without "acpi=off noapic", <= 4.5.7 can reboot and shutdown, but later kernels hang during both reboot and shutdown.
Since I can't run the ancient kernels forever, I'm adding "acpi=off noapic" and will just live with the hang during shutdown. Fortunately, the filesystem appears to close before hang, so I don't have filesystem corruptions when I start up the next time.
