Maybe I messed up with bisect trying to find the origin of two regression. One was this. The other one is this one. Hibernation (to disk, of course) doesn't work no more. Screen blanks and nothing happens. No HD activity, and so on. I also waited some minutes. Well, bisect blame this commit: commit 2a4f0c81adcd1f812a63bc9106be2fd26f437730 Author: Mattia Dongili <malattia@xxxxxxxx> Date: Sat Feb 19 11:52:30 2011 +0900 sony-laptop: cache handles and report them via sysfs Avoid calling into acpi each time we need to lookup a method handle and report the available handles to ease collection of information when debugging issues. Also move initialization of the platform driver earlier to allow adding files from other setup functions.
