Problem with shutdown button not firing ACPI event



Hello List,

I'm trying to get my shutdown button to work, but I can't seem to figure it out. When I press the button, nothing is received when I listen to ACPI events using acpi_listen.

dmesg | grep -i acpi displays the following information:

If the event was received and Linux wouldn't be doing anything with it, I could deal with it. But the event doesn't fire at all so I have no idea where to look. I'm running F10, kernel version 2.6.27.41-170.2.117.

Does anyone have an idea what the problem is?

Regards, Gijs
