apt-get autoremove crashes my system

[jean-christophe manciot]

Ubuntu 15.04 Server Gnome - 3.19.0-25-generic #26-Ubuntu SMP Fri Jul 24 21:17:31 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
apt 1.0.9.7

If I try to clean my system with "sudo apt-get autoremove":

After this operation, 338 MB disk space will be freed.

If answer Yes to that, and reboot, I land on the non-graphical login.
After restoring the system just before the "apt-get autoremove", I am able to show the differences in the syslog:

It seems that maybe acpi-support should not be removed for example.
