From: Michal Hocko on 1 Apr 2010 09:40 Hi Rafael, Matthew, my laptop changed behavior during poweroff recently (after upgrading from .33 to .34-rc1). The system seems to be powered off (status display is off) at first glance but when I close the lid then I can hear a noise which sounds like HDD parking and when I open lid again it starts booting without poweroff button (same like when I suspend to RAM). I have bisected that down to the following commit: commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78 Author: Rafael J. Wysocki <rjw(a)sisk.pl> Date: Wed Feb 17 23:41:07 2010 +0100 ACPI: Use GPE reference counting to support shared GPEs ACPI GPEs may map to multiple devices. The current GPE interface only provides a mechanism for enabling and disabling GPEs, making it difficult to change the state of GPEs at runtime without extensive cooperation between devices. Add an API to allow devices to indicate whether or not they want their device's GPE to be enabled for both runtime and wakeup events. Remove the old GPE type handling entirely, which gets rid of various quirks, like the implicit disabling with GPE type setting. This requires a small amount of rework in order to ensure that non-wake GPEs are enabled by default to preserve existing behaviour. Based on patches from Matthew Garrett <mjg(a)redhat.com>.

Wysocki <rjw(a)sisk.pl> Signed-off-by: Jesse Barnes <jbarnes(a)virtuousgeek.org> When I revert this commit, the system behaves like before. I am not sure which kind of information might be useful so I have attached only config file for now. The laptop is Futjitsu Siemens Lifebook S Series. Let me know what else might help for further investigation. Thanks and best regards -- Michal Hocko L3 team SUSE LINUX s.r.o. Lihovarska 1060/12 190 00 Praha 9 Czech Republic

Hm. At a guess, we're somehow managing to leave the lid GPE enabled at poweroff. Can you send the output of the acpidump command? -- Matthew Garrett | mjg59(a)srcf.ucam.org -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Please also send the contents of /proc/acpi/wakeup.

I have checked both kernels (with and without reverted 9630bdd) and the output looks pretty much same. 2.6.34-rc3, however, looks different a bit, so I am attaching it as well. > > Rafael -- Michal Hocko L3 team SUSE LINUX s.r.o.
