For what it's worth, booting with "acpi=off" seems to reliably avoid the hang, although it comes with side effects an therefore isn't really a good workaround. None of the other acpi-related boot options mentioned at <https://01.org/linux-acpi/documentation/debug-how-isolate-linux-acpi-issues> seem to help.
So far, booting with the 4.3.5 wily kernel seems to be the most usable workaround..
