Hi! With a recent RELENG_6 I've experienced what I suspect to be an ACPI issue. When powering down the system using `halt -p' I'm seeing a message like 'power off using ACPI' after the system has been shut down but the system does not power off. I've seen this yesterday with a csup'ed system as of yesterday and also today (csup'ed last night). I haven't had issues like that on this system before (using RELEASE-anything or an older RELENG_6 ACPI power off did work on that hardware). Following is my dmesg. If you need to see something more (like ACPI tables) please advise. Greetings, Volker Copyright (c) 1992-2006 The FreeBSD Project.
