Message-ID: <76366b180809162150o51701a1fk209af4e84ffc5674@mail.gmail.com> Date: Wed, 17 Sep 2008 00:50:03 -0400 From: "Andrew Paprocki" <andrew@...iboo.com> To: LKML <linux-kernel@...r.kernel.org> Subject: ACPI "Soft-off" power button only rebooting system, not powering off I have an AMD / Award BIOS based system which does not properly shut off when I hold down the power button for 4 seconds. The BIOS is configured to have "Soft-off" set to "Delay for 4 seconds" which is supposed to power the machine off if the button is held that long. I first thought this could be a BIOS bug, but this *only* appears to happen while Linux is running. If the computer is running WinXP, it works fine. Also, if I hold down the button for 4 seconds while the BIOS is in POST, it also works fine. If the kernel has booted, even if the kernel is not running anymore due to a `halt`, holding the button down merely reboots the PC after 4 seconds. Can anyone offer a place to start poking around to see why this only happens when Linux is running? Would this have to do with the ACPI code itself? The kernel version does not seem to matter. I first noticed this on stock Debian 2.6.18-4, and I just reproduced it right now using 2.6.26.5.
