Bug#775812: base: HP EliteBook 840 G1 laptop fails to halt/poweroff after 15/12/2015 upgrade

[Miguel Ortiz Lombardía]

Hi,

Attached a file listing what was upgraded via apt on December 15, the
day I first noticed the problem. I halt the computer every day, so that
should be in principle the first day it refused to do so properly.

I use what I think is the default init system in jessie, i.e. systemd/udev.

I hope this may help understand the issue.

Best regards,

   Miguel
