I'm running stable on an amd64 PC since wheezy release. Until recently, I was able to nicely suspend and resume the system by pressing the hardware "power" button on the chassis.
After a recent update (not sure which packages are involved, as a lot of time has passed since the last update on that machine), I noticed that when I press the power button the system starts to suspend, but at the same time a shutdown is started - I can get a glimpse of the message:Power button pressed.as it appears on all terminals just before the screen blanks. As a result of this, as soon as the system completes the resume, it goes on and continues with the shutdown and the machine powers off.I'm using GNOME classic session.How do I debug this? Where do I begin?
