From 79d2dfaa4e787f94b7f65f4611bc7d1c8d85fabc Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Fri, 24 Aug 2007 01:24:47 -0400 Subject: ACPI: enable GPEs before calling _WAK on resume It seems it's required to enable GPEs before _WAK. E.g. X60 triggers a LID related GPE instead of doing a Notify in WAK. Now the GPE reaches the kernel and the Notify for LID status change gets thrown from there.
