Comment 96 for bug 1419355

Well this morning coming back from a 4 days holiday, as a miracle, the shutdown of my Ubuntu 14.04 returned to work properly without any change made by me.
I do not know what patches Canonical has made. My kernel remains:
mariora@mariora-desktop:~$ uname -r
3.13.0-35-generic
Tell ma what I can do for understanding what was updated in the system for solving the issue
