When you have a system which logs the following but doesn't halt, what should you investigate?

Fiddle with ACPI DSDTs and so on. What I *actually* do it put a sticker on the front that says "OS cannot turn off power, use power button after OS is halted". Possibly apropos: But other times there's no need for the difference. For years we were triggering system reboots in a different way to Windows and then adding DMI workarounds for any systems that didn't work. The problem with this approach is that it's basically impossible to guarantee that you've found the full set of broken hardware. It's very easy to add another DMI quirk, but it doesn't solve the problem for anyone who bought a machine, tried Linux and gave up when they found reboot didn't work. -- http://mjg59.dreamwidth.org/14475.html (That's from "the UEFI guy", not "the ACPI guy".)
