Comment 2 for bug 1455520

I have same behavior on debian jessie
it's occurs only where resume from ram..but not if resume from disk (hibernate)

i try to insolae the problem. i start with mate-power-manager (from mate-desktop):
https://github.com/mate-desktop/mate-power-manager/issues/140
But seems that it's not their fault

i think that when resume pressing the powerbutton , its wakeup the machine but also send the poweroff event that poweroff the machine after 20 or 30 seconds.
