[regression] Hibernate no longer works
Until recently, hibernate worked on my Dell XPS 13 Developer Edition (the production model sold starting in late November 2012). After recent updates, it no longer works. Choosing Hibernate from the shutdown menu seems to hibernate, but pressing the power button to resume from hibernate just boots the computer normally. i.e., the hibernated state is gone.
There are some kernel warnings briefly visible on the screen while hibernating. I'll try and memorize them and add them here.
