Looks like you nailed it. I got home from vacation, updated to the latest -current, confirmed it was still broken, and applied your patch (which still applied cleanly). I had to change a couple of identifiers to make it compile: APIC_TRIGGER_LEVEL ==> TRIGGER_LEVEL APIC_POLARITY_ACTIVEHI ==> POLARITY_ACTIVE_HIGH I assume those were just typos, and I hope I guessed the right replacements. Anyway, now the system boots and runs fine with ACPI enabled, and things like "shutdown -p" do the right thing. Thanks! Your patch looks like a keeper. John
