Message-ID: <470C9731.6030200@free.fr> Date: Wed, 10 Oct 2007 11:11:13 +0200 From: John Sigler <linux.kernel@...e.fr> To: linux-kernel@...r.kernel.org, linux-acpi@...r.kernel.org CC: robert.moore@...el.com, len.brown@...el.com Subject: Re: halt does not shut the system down (The original message seems to have been ignored by the mailing list robot, probably because the attachments made it too large. Re-send with links instead of attaching the documents to the message.)
